Design the folded-cascode circuit of Fig. to provide voltage gain of 80 dB and a unity-gain frequency of 20 MHz when CL = 10 pF. Design for IB = I, and operate all devices at the same / VOV / Utilize transistors with 1-μm channel length for which / VA/ is specified to be 12 V. Find the required overdrive voltages and bias currents. What slew rate is achieved? Also, for k1n = 2.51p = 400 μA/V2, specify the required width of each of the 11 transistors used.
