Node Voltage Method

Node Voltage Method: The node voltage method can also be used with networks containing complex impedances and excited by sinusoidal voltage sources. In general, in an N node network, we…

Mesh Current Equation

Mesh Current Equation: We have earlier discussed meth analysis but have applied it only to resistive circuits. Some of the ac circuits presented in this chapter can also be solved…

Performance of Circuit Breaker System Requirements

Performance of Circuit Breaker System Requirements: Analysis of circuit interruption and the foregoing discussion of various circuit breakers apply to circuit breakers in practice if they had ideal switching characteristics.…

Wein Bridge Oscillator using Op Amp

Wein Bridge Oscillator using Op Amp: The Wein bridge is an ac bridge that balances only at a particular supply frequency. In the Wein Bridge Oscillator using Op Amp (Fig.…

Colpitts Oscillator using Op Amp

Colpitts Oscillator using Op Amp: The Colpitts Oscillator using Op Amp circuit show in Fig. 16-4 is similar to the op-amp phase shift oscillator, except that an LC network is…

RC Phase Shift Oscillator Circuit Diagram

RC Phase Shift Oscillator Circuit Diagram: Figure 16-1 shows the RC Phase Shift Oscillator Circuit Diagram, which consists of an inverting amplifier and an RC phase-shifting network. The amplifier phase-shifts…

Stray Capacitance Effects

Stray Capacitance Effects: Stray Capacitance Effects (Cs) at the input terminals of an operational amplifier effectively introduces an additional phase-lag network in the feedback loop, (see Fig. 15-17), thus making…

Voltage Series Negative Feedback Amplifier

Voltage Series Negative Feedback Amplifier: In a negative feedback amplifier, a small portion of the output voltage is fed back to the input. When the feedback voltage is applied in…
