Question
(b) Derive expressions for the break frequencies caused by Cp and Cc. (c) Give an expression for the amplifier voltage gain A(s). (d) For Rsig = Rc= R¸ = 10 kN, ß= 100, and I = 1 mA, find the value of the midband gain. (e) Select values for C, and C, to place the two break frequencies a decade apart and to obtain a lower 3-dB fre- quency of 100 Hz while minimizing the total capacitance. (f) Sketch a Bode plot for the gain magnitude, and estimate the frequency at which the gain becomes unity. (g) Find the phase shift at 100 Hz. C
