Question

Design the circuit to obtain a dc gain of 20 db, a 3-db frequency of 5 khz, and an input resistance of 2k. Hint: see example 2. 4 in page 88 of our textbook. Write your answer rounding to 2 significant digits. Examples: 0. 35, -2. 4, 13, -920

Answer 1

Answer: Your welcome!

Step-by-step explanation:

The circuit to obtain a DC gain of 20 dB, a 3-db frequency of 5 kHz, and an input resistance of 2k is a two-stage amplifier with a common emitter stage and a common collector stage. The first stage has a DC gain of 10 dB, a 3-db frequency of 2 kHz, and an input resistance of 2k. The second stage has a DC gain of 10 dB, a 3-db frequency of 5 kHz, and an input resistance of 10k. The overall DC gain is 20 dB, the 3-db frequency is 5 kHz, and the input resistance is 2k.
