Voltage Level Translator (Level Shifter): Voltage Level Translator (Level Shifter) is usually an emitter follower circuit which is used to shift the dc level at the output of the intermediate…

JFET Differential Amplifier - Circuit Diagram and its Workings: Many differential amplifiers are constructed with FETs because of the large impedance they present to the input signals—an exceptionally important property…

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…

Swamping Resistor in Differential Amplifier: The dependence of the voltage gain of the differential amplifiers on variations in ac emitter resistance r′e can be reduced and also the linearity range…

Single Input Unbalanced Output Differential Amplifier: Single input unbalanced output differential amplifier configu­rations are rarely used. The reasons for this are as follows: This configuration is identical to the CE…

Single Input Balanced Output Differential Amplifier: In a single input balanced output differential amplifier an input signal is applied to either input, with the other input connected to ground. However,…
