Unformatted text preview: take Ccbi=0 2 RL RL Io Vin+ VinVout+ VoutRgen Rgen A) For Io=3 mA, IoRL=300 mV, Rgen=RL, please find the small signal voltage gain of the circuit and the small signal input impedance. Exploit symmetry. Use nodal analysis or MOTC to find the high frequency response (gain as a function of frequency) Under limiting conditions (one transistor on, other off, what is the maximum output voltage, and what approximate input voltage is required to obtain this). RL RL Ics RL RL Ics Ief Ief b) Multistage bipolar amplifiers tend often to look like the ckt on the left…lets take a onestage slice of this, as in the next figure… 50 50 Vout+ VoutRL RL Ics Ief Ief Vin+ 50 50 Vin…based upon this, find the smallsignal voltage gain Vout/Vin of this circuit at low frequencies. 3...
