Amplifiers with Negative Feedback

Emitter Current Feedback Circuit

Emitter Current Feedback Circuit: Emitter Current Feedback Circuit is produced by connecting an unbypassed resistor in series with the emitter terminal of a transistor, as shown in Fig. 13-24(a). The effects of an unbypassed emitter resistor in a CE circuit have been analyzed already, where it is shown that the circuit impedance and voltage gains …

Two Stage CE Amplifier using Series Voltage Negative Feedback

Two Stage CE Amplifier using Series Voltage Negative Feedback: Negative Feedback Amplifier Circuit – A two-stage, capacitor-coupled BJT amplifier is shown in Fig. 13­-10. This is the same Two Stage CE Amplifier circuit discussed already with the addition of feedback components RF2, RF1, and CF1. The output voltage is divided across RF2 and RF1 to produce a feedback …
