Unformatted text preview: ω ) 2 and phase{H( ω )} on a Bode plot. 2. Consider the circuit sketched to the right. The opamp has “ideal” input and output resistance, but its gain is A(s). (a) Find the feedback transfer function B(s) = V /V OUT . (b) Write H (s) in terms of A(s) and B(s). (c) Assume A(s)=G/s, put in your result for B(s), and write H(s) as a rational function of s. (d) Write the loop gain T(s) as a rational function of s. (e) Plot the magnitude and phase of T( ω ) on a Bode Plot. (f) Find the phase margin....
