Unformatted text preview: VGT(lower)=VGT(upper) only @0.7V cutoff for VG<0.7V would be sat at VG = 0.7, but current still 0 lower transistor in linear for VG>0.7V upper in saturation 5a) sat B = 6mA/v 2 ; I = 0.03mA 5b) cutoff 5c) sat I = 3*0.2 2 = 0.12mA 5d) same as 5c) 6) .1mA = (B/2)(0.9-0.7) 2 (1+0.01) B = 4.95mA/v 2 W/L = 49.5...
