Two Stage Direct Coupled BJT Amplifier 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 into negative feedback amplifiers by following the same procedure. Similarly, BIFET circuits, both Two Stage Direct Coupled BJT Amplifier […]

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 […]
