Non Inverting Amplifier Theory: Direct-Coupled Noninverting Amplifier - The Non Inverting Amplifier Theory circuit in Fig. 14-14 behaves similarly to a voltage follower circuit with one major difference. Instead of…
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…
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…
BIFET Amplifier: BJT-FET Considerations : Two-stage BJT circuits usually have relatively low input impedances. To increase Zi, a field effect transistor may be used as the first stage. Circuits which…
DC Feedback Pair with Two Amplification Stages: The DC Feedback Pair with Two Amplification Stages circuit shown in Fig. 12-25(a). The base of transistor Q2 is directly connected to the…
Two Stage Direct Coupled Common Emitter Amplifier: Figure 12-23 shows Two Stage Direct Coupled Common Emitter Amplifier. This time the second stage is a common collector circuit, or emitter follower.…
Frequency Response of FET Amplifier: Low-Frequency Response - The low Frequency Response of FET Amplifier circuits is determined by exactly the same considerations as for BJT circuits. The lower cutoff…
Coupling Capacitors: Coupling Capacitors are required at a circuit input to couple a signal source to the circuit without affecting the bias conditions. Similarly, loads are capacitor-coupled to the circuit…
