Using the topology seen in Fig. 22.26 with the long-channel process (Table 9.1) without body effect (all MOSFET's bodies tied to their respective sources), show that the currents in M1-M4 match the biasing currents used in the source followers. Show how the currents become mismatched when the bodies of the NMOS are tied to ground and the bodies of PMOS are tied to VDD.
