Question

Transcribed Image Text:We wish to design a three-stage
amplifier. To make the problem simple,
we do not consider the Early effect. And
VBE for Q2 and Q3 is 0.7 V.
Choose all the required resistances except
for RDI and RS1.
All capacitors are supposed to be big
enough to be shorted at the frequency of
interest.

Note that you need to DC analysis first. Do a hand calculation and calculate the DC collector current or IC. This is needed in order to calculate the small signal parameters gm and rπ and in turn to obtain the Av , Ri and Ro Hence, first perform a DC analysis (use the circuit in Figure 1 and take all capacitors open) and assume your transistor has a β=140.arrow_forwardPlease solve with steps, using to study.
