5.36 Consider the circuit in Fig. P5.29 with both transistors perfectlymatched butwith the dc voltage at the drain ofQ1 lowered to +2 V. If the two drain currents are to be matched within 1% (i.e., the maximum difference allowed between the two currents is 1%), what is the minimum required value of VA ? If the technology is specified to have VA = 100 V/μm, what is the minimum channel length the designer must use?
