Suppose that you are designing an intermediate frequency amplifier like the one shown below • 12 VOLTS 68K BRL IK C) VouT 22K } IK VW Та CE 7 Figure 1: An intermediate frequency amplifier In the above the transistor current gain is 80, the common base output capacitance Co = 2 pF, the transition frequency fr = 1 x 10% Hz, r, is quite high (so can be neglected). So, a) Find Rsuch that the gain of the amplifier equals to 200 in magnitude. b) Determine the -3 d8 point of the amplifier 1 c) Discuss the addition of a possible feedback resistor from collector to base that will improve the bandwidth of the amplifier to 1800 KHz.
