Consider the circuit of Fig. 4.23(a). In Example 4.5 it was found that when V, 1 V and k;(W/L) = 1 mA/V, the drain current is 0.5 mA and the drain voltage is +7 V. If the tran- sistor is replaced with another having V,= 2 V and k(W/L): 2 mA/V, find the new values of Ip and Vp. Comment on how tolerant (or intolerant) the circuit is to changes in device parameters. %3D Vop = +10 V Ra = 10 MN Rp = 6 kN Re = 10 Mn Rs = 6 kn (a) FIGURE 4.23 (a) Circuit for Example 4.5.
