Square Law Detector Circuit and Working Principle: The square law detector circuit is used for demodulating moduÂlated signal of small amplitude (i.e., below 1 V) so that the operÂating region…
Generation of DSBSC Signal using Balanced and Ring Modulator: DSBSC signal can be obtained by simply multiplying the modulating signal with the carrier signal. By simple multiplication of Vc sin ωct…
Output Stage of an Op Amp and its Voltage Transfer Characteristics: The output stage of an op amp is another requirement which should have very small output impedance and provide…
What is Current Mirror? - Circuit Diagram and its Workings The two-transistor current source, also called a current mirror, is the basic building block in the design of integrated circuit…
Constant Current Bias in Differential Amplifier: In the differential amplifiers discussed so far, we have used the combination of RE and VEE to produce emitter dc bias current. Alternatively, constant…
