☞Rule-6   Abstract nouns usually take singular verbs. Examples Truth eventually prevails. Hatred has no limit. The fragrance of this perfume is so overpowering. ☞Rule 7.   When sentences start with “there” or “here,” the subject will always be placed after the verb, so care needs to be taken to identify it correctly. Examples: There are four hurdles to jump. Here are the keys. There is a problem with the balance sheet. Here are the papers you requested. ☞Rule 8.   Titles of books, movies, novels, etc. are treated as singular and take a singular verb. E.g. The Burbs is a movie starring Tom Hanks.

E.g. Standing in the water was a bad idea. Swimming in the ocean and playing drums are my hobbies. ☞Rule ...

SUBJECT AND VERB AGREEMENT) ☞Rule-1   When a lot of, a great deal of, plenty of, most of and some of refer to plural numbers, a plural verb is used. E.g. A lot of people were present in the party. Some of the students were absent. But, if these expressions refer to an amount, the verb is in the singular number. E.g. A lot of work has to be completed before we go. A great deal of work has been finished. ☞Rule-2  When the percentage or a part of something is mentioned with plural meaning the plural verb is used. E.g. 30 % of Indian women are literate. ☞Rule-3   Barracks, Headquarters, Whereabouts, Alms, Species, Sheep, News, Deer, Premises, Shambles etc. remain same in singular as well as plural form. E.g.-The company’s headquarters is based in New York. They tried to disrupt communications between the two headquarters. ☞Rule-4   In sports, while referring to the players, the name of the country is followed by plural verb. E.g. England have won the World...

Hello Readers, Enough of the philosophical treatment of GATE exam and now let’s get straight to business. Now I will be tackling the question which troubles the aspirants the most. Which Books to refer? Engineering Mathematics For studying the concepts you can refer to  Advanced Engineering Mathematics by E.Kreyszig. It covers all the topics in sufficient enough detail but kindly study this book with the GATE curriculum alongside you so that you don’t get lost in the vastness of this book. We have launched our  Kreatryx   Engineering Maths Book for GATE / ESE / PSU  Preparation available for EE / ECE / ME / CE  IN streams on Amazon.

Many of the students who are preparing for GATE may have a lot of doubts regarding how to set up a schedule and what to study to maximize the advantage and score more in the exam. This idea is also popular as ‘smart work’ among the students who may have probably formed some opinions about what this actually means. This article contains some of my opinions and the general ideas about what practices could be helpful in increasing your level and could provide maximum increase in the performance with minimum efforts – 1) Preparing a basic timetable in the beginning of a topic might be very helpful. Keep an account of the time period in which you aim to finish it and also sort the study material that you will go through. Try to follow the plan no matter what the others are doing or following and this plan should be based on GATE Previous Year Papers. 2) Try solving the unsolved problems first rather than looking at the solutions of examples given as it develops the ability to think i...

In this topic, you have to study the working of 555 Timer IC and the role of various terminals. After getting a basic idea of working you can understand how to realize the Mos-stable and Astable Multivibrator using 555 Timer IC. You have to learn about the time period and duty cycle of these multivibrators. If you can follow this post and study the topics mentioned in detail then I don’t think there will be any question in Analog Electronics that will trouble you. But make sure to change the mindset and approach this subject from Network Analysis point of view rather than Electronic Devices.

     This chapter begins with the study of Differential Amplifiers and then the basic characteristics of Op-Amp such as Offset Voltage and Current, Bias Current, Slew Rate, CMRR, SVRR, etc. Then you have to study about the differences between Ideal and Practical Op-amp. Also, study the model of the practical op-amp which includes Input Resistance and Output Resistance also. Then comes the most important concept in Op-Amp which is the concept of Virtual Ground. Based on this concept you have to understand the concept of Inverting Amplifier, Non-Inverting Amplifier, Inverting Summer, Non-Inverting Summer, Differentiator, Integrator, Current to Voltage Converter, Voltage Follower, etc. You should be able to solve any random circuit including Op-Amp using this concept.       Then you have to study the non-linear applications of Op-Amp such as Precision Diode, Half Wave Rectifier, Full Wave Rectifier, Log Amplifier, and Anti-log amplifier. Then using t...

This topic begins with the understanding of Barkhausen Criteria and then different types of oscillators such as RC Phase Shift Oscillator, and Wein Bridge Oscillator which are also called as Audio Frequency Amplifier. Then we have to study about the Radio Frequency Oscillator such as Hartley Oscillator, Colpitt Oscillator, Clapp Oscillator, and Clapp Oscillator. You also have to study the stability of Oscillator and Figure of Merit.

If you are clear about the analysis of BJT then understanding MOSFET should be a cakewalk. You have to start from the same point where you started BJT from that is the basics of the device and the current-voltage equation. Then based on characteristics of the device you have to understand the different operating regions of MOSFET which are cut-off, Linear and Saturation. Then you can move onto the biasing techniques of MOSFET which are identical to BJT but the main difference is that Gate current is zero due to insulator between gate and device. After the biasing you can study about the small-signal model of the device and the best part is that there is only one model that you have to study which is the Hybrid-pi model and you have to understand the amplifier analysis using this model. Also, you must know how to derive certain parameters like Trans-conductance and Output Resistance using DC Analysis. Again you will derive the same parameters as in BJT which are Voltage Gain, Inpu...

Again because of basic knowledge about Electronic Devices you do not need to study about working of BJT in detail and you can directly come to different configurations of BJT which are Common Emitter, Common Base, and Common Collector and about the various operating modes of BJT which are cut-off, Active and Saturation. Then you can study about biasing techniques in BJT which are Fixed Bias, Self Bias, and Voltage Divider Bias and in each of these configurations you need to understand how to compute the stability factor. By calculating Stability Factor you can determine the relative stability of each configuration. To improve the thermal stability you can also study about Compensation Techniques such as Diode Compensation, Thermistor, and Sensistor Compensation. Based on this knowledge you can study about DC applications of BJT such as Voltage Regulator by the use of the combination of BJT and Zener Diode. Also the concept of Current Mirror and Current Steering Circuits. Af...

Hi Guys, As per the request from many ECE guys for a post regarding Analog Electronics important topics, I am writing this post for them. Analog Electronics is one of the most important subjects for ECE and also since it is a core subject so it becomes much more important that this subject is covered in detail. But many GATE Aspirants are often confused as to what specifically we need to study from this subject as this subject is very vast in itself. This subject accounts for 10-12 marks in GATE exam and is very important if someone wants to pursue higher studies in Electronics domain. So, to reduce the effort we need to target the topics that are specific to GATE. Diode Circuits ECE guys will be very much aware of working of Diode in detail since they would have studied the same in Electronic Devices so they do not need to bother much about it. You can directly start from the current-voltage equation of diode and then proceed to Open Circuit and Short Circuit tests on...
