Differential Input and Differential Output Amplifier

Electronics Engineering, OP-AMP with Negative Feedback

Differential Input and Differential Output Amplifier: In almost all the applications, the op-amp is employed with a single-ended or unbalanced output. However, there are certain applications in which a differential output is desired. The differential input and differential output amplifier is widely employed as a pre-amplifier and in driving push-pull arrangements. One possible arrangement of …

Op Amp Differential Amplifier Circuit Diagram and its Operation

Electronics Engineering, OP-AMP with Negative Feedback

Op Amp Differential Amplifier Circuit Diagram and its Operation: An ideal difference amplifier amplifies only the difference between two signals; it rejects any common signals to the two input terminals. For instance, a microphone system amplifies an audio signal applied to one terminal of a difference amplifier, and rejects any 50 Hz noise signal or …

CMRR of Op Amp Formula (Common Mode Rejection Ratio)

Electronics Engineering, Operational Amplifiers and their Parameters

CMRR of Op Amp Formula (Common Mode Rejection Ratio): One of the more common features of a differential amplifier is its ability to cancel out or reject certain types of undesired voltage signals. Such undesired signals are referred to as “noise” and may occur owing to voltages induced by stray magnetic fields in the ground …

Blocking Oscillator – Definition, Operation and Types

Electronics Engineering, Switching Circuits

Blocking Oscillator – Definition, Operation and Types: The output of an active device may be coupled back to the input through a pulse transformer. If the relative windings polarities are properly chosen, the feedback will be regenerative and the circuit can be made to generate a single pulse (monostable operation) or a pulse train (astable …

Commutating Capacitor in Bistable Multivibrator or Speed up Capacitor

Electronics Engineering, Switching Circuits

Commutating Capacitor in Bistable Multivibrator or Speed up Capacitor: Commutating Capacitor in Bistable Multivibrator is also called as Speed up Capacitor. Whenever a triggering pulse is applied to change the bistable state from one bistable state to another, it is necessary that the transition period should be minimum and it should require minimum but finite …
