We wish to investigate the performance of the EC amplifi er of at two extremes, one being when emitter bias is provided entirely by the IEE source and thus REE 5 `, and the other being when it is provided entirely by the REE resistance and thus IEE 5 0. Let VCC 5 2VEE 5 12 V and RC1 5 RC2 5 10 kV, and let the BJTs have 0 5 160 and VA 5 50 V (assume r 5 `). (a) Find adm, acm, Rid, Ric, and the CMRR (both for single-ended and double-ended utilization) if IEE 5 1 mA and REE 5 `. (b) Repeat, but with IEE 5 0 and REE 5 11.3 kV. Compare the two cases and comment.
