Power Supply Decoupling: Power Supply Decoupling - High-power amplifiers require high supply current levels, so unregulated power supplies are often employed to avoid the power wasted in a series regulator.…
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,…
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…
Direct Coupled Circuits: For economy, the number of components used in any circuit should be kept to a minimum. The use of direct coupling between stages is one way of…
Capacitor Coupled Two Stage CE Amplifier: A Capacitor Coupled Two Stage CE Amplifier circuit is shown in Fig. 12- 15 . Stage-1 is capacitor-coupled (via C3) to the input of…
