Step Down Converter: A step-down switching regulator, or Step Down Converter (also termed a buck converter), produces a dc output voltage lower than its input voltage. The basic circuit arrangement…
Switching Regulator Operation: A Switching Regulator Operation can be thought of as similar to a linear regulator, but with the series-pass transistor operating as a switch that is either off,…
Short Circuit Protection Circuit: Power supplies used in laboratories are subject to overloads and short circuits. Short Circuit Protection Circuit by means of current limiting circuits is necessary in such…
Improving Regulator Performance: Error Amplifier Gain - The performance of a regulator is dependent on the voltage gain of the error amplifier. A higher gain amplifier gives better line and…
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: 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…
Biasing Bipolar Op Amp Circuit: Biasing Bipolar Op Amp Circuit - Like other electronic devices, operational amplifiers must be correctly biased if they are to function properly. As already discussed,…
