In the SC circuit of let VDD 5 2VSS 5 2.5 V, RD1 5 RD2 5 10 kV, ISS 5 0.2 mA, and RSS 5 200 kV. Moreover, let the FETs have k 5 1.25 6 2% mA/V2 , Vt 5 0.6 V 6 1% V, 5 1y(15 V), and 5 0.2. (a) Using nominal parameter values, fi nd adm and acm. (b) Investigate how the above tolerances affect the CMRR for the case of double-ended utilization. Find its value, in dB, both for the worst-case scenario and the case in which the tolerances are uncorrelated. Hint: develop an expression for Dgmygm in terms of Dkyk and DVOVyVOV.
