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…
Differential Amplifier With Three OP Amp: Differential Amplifier With Three OP Amp, depicted in Fig. 34.47 consists of two stages—one formed by op-amps A1 and A2 and second by op-amp A3. Hence for determination of overall…
Differential Amplifier with two Op Amps: The gain as well as input resistance of the differential amplifier can be increased by using two op-amps. The characteristics of such an amplifier are identical to those of…
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…
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…
Op Amp IC 741 Pin Diagram and its Working: The schematic diagram and Op Amp IC 741 Pin Diagram is shown in Fig. 33.4 (a) and in Fig. 33.4 (b). It is not necessary to…
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…
Triggering in Digital Electronics | Types: Triggering in Digital Electronics is the process of applying an external signal to induce transition from one state to another. The signal used for triggering is either a pulse…
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…
Bistable Multivibrator - Working and Types: A bistable multivibrator, as its name implies, has two stable states. It can stay in either of the two states indefinitely (as long as dc power supply remains on).…
