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. |
