Shown in Fig. P6.17 is the ac equivalent of a CMOS differential amplifi er driving a load consisting of RL and CL. Let all FETs have gm 5 2.5 mA/V, 5 0.2, ro 5 100 kV, fT 5 750 MHz, Cgd 5 30 fF, and Cdb 5 100 fF. Moreover, let RG 5 3.0 kV, RD 5 20 kV, RL 5 75 kV, and CL 5 0.45 pF. (a) Use the half-circuit technique to fi nd the lowfrequency value as well as the zero frequency and the two pole frequencies of adm(jf). What is the GBP of this amplifi er? (b) Use the half-circuit technique to estimate the low-frequency value as well as the zero frequency of acm(jf) if RSS 5 1 MV and CSS 5 50 fF.
