For a cascode current source such as that in Fig. 8.32, show that if the two transistors are identical, the current I supplied by the current source and the output resistance Ro are related by IRo = 2 /VA/2 / /VOV / Now consider the case of transistors that have /VA /= 4 V and are operated at /VOV / of 0.2 V. Also, let μpCox = 100 μA/V2. Find the W/L ratios required and the output resistance realized for the two cases: (a) I = 0.1 mA and (b) I = 0.5 mA. Assume that VSD for the two devices is the minimum required (i.e., /VOV /).
