In all ΟΤA problems, the specifications are: gm − IABC sensitivity = 20, maximum gm = 1 mS with range of 4 decades.

In the Tow-Thomas biquad in Fig. 8.57, C1 = 20 pF, C2 = 10 pF, gm1= 10 μS, gm2= 80 μS, and gm3= 10 μS. Find the low-pass filter transfer function for the vi1 − vi2 input-output pair. Plot the corresponding Bode plot.
