P3.13 Consider the circuit shown in Figure P3-I3. (a) Write an analytical expression for the circuit\'s 3-dB bandwidth using an OCT analysis. (b) Determine the exact analytical result for the circuit\'s 3-dB bandwidth. (c) Compute the percent-error of the result in part (a), relative to the accurate result of part (h). Solution V0 = R/(1+sCR) *g12 Vs2 Vs2 = R/(1+sCR) *gm Vx1 Vx1= 1/(1+sCR) Vs s = d/dt V0/Vs= R*g12*gm/(1+sCR)3.
