For the op-amp circuit below, find vo. Assume that vs changes abruptly from 0 to 1 V at t-0. Find vo. R1 20K, R2 10K, C -.5HF Copyright The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Solution consider the laplace forms Z in the feed back is R2 + 1/sC = R2/1+sCR2 Vo/Vi = -Z/R1 = -R2/R1 (1/1+sCR2) = -1/R1C * 1/(s + 1/R2C) So in time domain i.e applying inverse laplace Vo/Vi = -1/R1C * e-t/R2 C so Vo(t) = -1/0.01 * e-t/ 0.005 * 1 for t>0 Vo(t) = -1/0.01 * e-t/ 0.005 for t >0.
