SCR as Half Wave Rectifier Circuit Diagram: SCRs are very useful in ac circuits where they may serve as rectifiers whose output current can be controlled by controlling the gate…
Linear Diode Detector or Envelope Detector: Diode detection is called the envelope detection as it recovers the audio frequency signal envelope from the composite signal. Diode detector is also called…
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…
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 configuÂrations 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,…
Dual Input Unbalanced Output Differential Amplifier: It is an important configuration and converts dual inputs into a single ended output. In this configuration, two input signals are applied and the…
