Consider that the phase shift of an RC coupled CE amplifier is 260°. Find the low frequency gain when the voltage gain of the transistor is -150.(a) 100(b) 26(c) 40(d) 55I got this question in an interview for job.My doubt stems from Low Frequency Response and Miller Effect Capacitance in section Transistor Frequency Response of Analog Circuits

Answer» RIGHT CHOICE is (b) 26

To elaborate: 180° + tan^-1(fL/f) = 260°

fL/f = tan(80) = 5.67

A = \(\FRAC{150}{\SQRT{1}}\) + 5.672 = 26.05.
