(a) For the CD push-pull stage of fi nd an expression for the quiescent current IQ in terms of the ID3, ID4, and the device transconductance parameters k1 through k4 (assume 5 0). (b) How does the expression for IQ simplify for the case of ideal current mirrors? (c) Calculate IQ for the component values shown in the fi gure.
