As we know, resistors are undesirable in MOS IC technology, so the circuit of Fig. P4.52 utilizes the diode-connected pair M3-M4 in lieu of the resistance pair RD1-RD2. Let VSS 5 2VDD 5 3 V, ISS 5 200 A, and RSS 5 `. Moreover, let the FETs have Vt n 5 2Vt p 5 0.4 V, k9 n 5 2.5k9 p 5 100 A/ V 2 , 5 0, and 5 0. (a) Obtain an expression for the gain a 5 vodyvid. (b) Find a relationship between the nMOS ratio WnyLn and the pMOS ratio WpyLp that will result in a 5 24 V/V. (c) Specify suitable values for WnyLn and WpyLp if the input is vid 5 (0.1 V)cos t. Impose 4VOVn 5 10 3 (0.1 V). What is vod? (d) Find the total (sum of the dc and ac components) signals vO1, vO2.
