Effects of Negative Feedback in Amplifiers:

Decibels of Feedback – Effects of Negative Feedback in Amplifiers can be measured in decibels. A statement that 40 dB of feedback has been applied to an amplifier means that …

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 …

Parallel Current Negative Feedback Circuit:

Current Feedback Circuit – In series-voltage feedback, a portion of the output voltage is fed back in series with the signal source. In Parallel Current Negative Feedback Circuit, a portion of …

Series Voltage Negative Feedback Amplifier:

Negative Feedback Concept – 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 series with …

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 …

Two Stage Differential Amplifier with Negative Feedback:

The circuit shown in Fig. 13-20 has a Two Stage Differential Amplifier with Negative Feedback with npn BJTs, and a direct-coupled pnp transistor differential amplifier second stage. The circuit …

Two Stage Direct Coupled BJT Amplifier Circuit:

The Two Stage Direct Coupled BJT Amplifier Circuit in Fig. 13-17 is reproduced from Fig. 12-22, and modified to include feedback components RF1 and RF2. Other direct-coupled circuits can be converted …
