Repeat Problem 11.22 if the MOS transistors in Fig. 8.48 are replaced by bipolar transistors. Assume that β = 200, r_b= 300, I_C= 1 mA and the flicker noise corner frequency is f_a= 5 kHz. Neglect capacitive effects.

Data from Prob. 11.22:

Calculate the total equivalent input noise current for the shunt-shunt feedback circuit of Fig. 8.48 in a bandwidth from 0.01 Hz to 100 kHz. Use the MOS transistor data in Problem 11.5. Ignore gate-current noise in (11.15) and (11.16).
