instrumentation amplifier is the extension of mcq

1. There are four different types of feedback topologies based on type of output signal and feedback signal (voltage or current signal). Class B amplifier: Class B amplifiers are biased at zero DC bias collector current. Its low input resistance finds application in specific areas where the signal strengths are very low (or) when load on source should be very low. It is basically a differential amplifier, that performs amplification of difference of input signal. 4. Choose the letter of the best answer in each questions. Instruments are subdivided into active and passive based on whether the output of instrument is produced by the quantity being measured simply changes the magnitude of some external power source. It is specified in units of ohms and is denoted by Rt. Class B amplifier: Class B amplifiers are biased at zero DC bias collector current.Hence it conducts only for half of the input signal cycle, so the conduction angle for class B amplifier is 180 Degrees. Where it is used? Practice Exam Test Questions . D) much less than 180° of the input cycle. Phase distortion will not create much problem in audio amplifiers. In complementary push pull amplifier neither an input nor an output transformer is needed. The offset drift is attributable to temperature-dependent voltage outputs. Noise with feedback = Noise without feedback* desensitivity factor (since desensitivity factor << 1 in negative feedback, hence Noise without feedback > Noise without feedback). The time during which the transistor conducts i.e. Class C amplifier: In class C amplifier the transistor conducts for an interval less than the half cycle. There are mainly four types of amplifiers based on conduction angle. Tuned amplifier is one in which a tuned circuit is introduced in to the output circuit which draws maximum power output only for a specified range of frequencies. A) voltage drop across the transistor is important. d)Voltage shunt: Output signal is voltage signal, feedback signal is current signal. The Q-point is at cutoff for class _____ operation. Band width with feedback = Band width without feedback/ desensitivity factor (since desensitivity factor << 1 in negative feedback, hence Band width without feedback > Band width without feedback). Requirements of a Good Instrumentation Amplifier Which class of amplifier operates in the linear region for only a small part of the input cycle? Tuned amplifiers are used in video and radio frequency applications. Non linear distortion with feedback = Non linear distortion without feedback* desensitivity factor (since desensitivity factor << 1 in negative feedback, hence Non linear distortion without feedback > Non linear distortion without feedback). What are types of power amplifier based on conduction angle? If you are looking for a reviewer in Electronics Engineering this will definitely help. Input resistance with feedback = Input resistance without feedback/ desensitivity factor (since desensitivity factor << 1 in negative feedback, hence Input resistance without feedback > Input resistance without feedback). Analog Devices instrumentation amplifiers (in-amps) are precision gain blocks that have a differential input and an output that may be differential or single-ended with respect to a reference terminal. The least efficient amplifier among all classes is. Which amplifier is commonly used as a frequency multiplier? Select an Op Amp. Home » Electronics » Questions and Answers » Floyd Questions and Answers ». It is specified in units of mhos (or) Siemens and is denoted by Rt. 23. We'll assume you're ok with this, but you can opt-out if you wish. Pinoybix.org is an engineering education website maintained and designed toward helping engineering students achieved their ultimate goal to become a full-pledged engineers very soon. It is employed in current amplifiers. ElectricalNotes4u is a Blog for Electrical Engineering Students who want to learn Electrical Engineering online. 1. A) slightly more than 180° of the input cycle. Special attention has to be paid in designing such amplifiers as the power dissipation across the junction raises its temperature and eventually destroys it. What is tuned amplifier? Where Rg = Rg1//Rg2, gm is Transconductance, Rd is the resistance at the drain terminal. ... Extension of Ammeter Range. C. averaging amplifier; D. summer and nonzero-level detector; 13. The principal advantage(s) of MOSFETs over BJTs is (are). Electronic Instruments - MCQs with answers Q1. Push pull amplifiers are more efficient than the single ended power amplifiers. Answered MCQ; Instrumentation amplifier is an extension of # Non inverting amplifier Inverting amplifier Summing amplifier Differential amplifier Comments and Answers (2) # 20 V. B. Also called as shunt-shunt feedback. MCQ in Operational Amplifiers from the book Electronic Devices and Circuit Theory 10th Edition by Boylestad. 12. What is class A, Class B, Class AB, Class C amplifiers? D) because the collector terminal is located nearest the case. It is often encountered in large signal amplifiers. 7. What is complementary push-pull amplifier? You have an application for a power amplifier to operate on FM radio frequencies. C) they can be connected in parallel for added drive capability. Explain why an ordinary junction transistor is called bipolar? Define Transconductance, Rd is the effect of ripple voltage that may be contained in the linear region only!
