6. For the digital circuit in Fig. 6, the NMOS transistor M₁ is used as a pass-transistor login, which passes logic level from V_x to V_Y. Assume,and the parasitic capacitance C = 100 fF. In consideration of the body effect, the threshold voltage of the NMOS device can be specified as

(c) Based on the charging currents in (a) and (b), please evaluate the propagation delay. [1%)
