13.8 A CMOS op amp with the topology in Fig. 13.1 has gm1 = gm2 = 1 mA/V, gm6 = 3 mA/V, the total capacitance between node D2 and ground is 0.2 pF, and the total capacitance between the output node and ground is 3 pF. Find the value of CC that results in ft = 50 MHz, and verify that ft is lower than fZ and fP2. Estimate the bias drain currents in Q1,2 and Q6 assuming |VOV| = 0.2 V for all transistors. 3.18 pF; 0.1 mA; 0.3 mA
