The shown S-R Flip Flop uses matched inverters and is fabricated in a 0.18 μm technology with μnCox = 400 μA/V2, (W/L)n = 0.45/0.18, and PMOST with μpCox = 160 μA/V2, (W/L)p = 1.125/0.18, VDD = 1.8 V, Vtn = |Vtp| = 0.4 V. The drain node capacitance CQ is equal to 100 fF and CR,S = 5 pF. The circuit is at RESET state. One of the shown sub-circuit needs to be used to change the state to SET. Select such a circuit and: Justify rejection of others Determine the clock time needed for the SET state to be ensured Determine the maximum clock frequency
