This problem investigates the effect of velocity saturation (Section 15.1.3) on the operation of a pseudo-NMOS inverter fabricated in a 0.13-um CMOS process for which VDD = 1.3 V, Vt = 0.4 V, kn = 5kp = 500 uA/V2, and |VDSsatp| = 0.6 V. Consider the case with vI = VDD and vO = VOL. Note that QP will be operating in the velocity-saturation region. Find its current IDsat and use it to determine VOL.

D 16.24 A 6T SRAM cell is fabricated in a 0.13−μm CMOS process for which VDD = 1.2 V, Vt = 0.4 V, and μnCox = 500 μA/V2. The inverters utilize (W/L)n = 1. Each of the bit lines has a 2-pF capacitance to ground. The sense amplifier requires a minimum of 0.2−V input for reliable and fast operation. (a) Find the upper bound on W/L for each of the access transistors so that VQ and VQ¯ do not change by more than Vt volts during the read operation. (b) Find the delay time Δt encountered in the read operation if the cell design utilizes minimum-size access transistors. (c) Find the delay time Δt if the design utilizes the maximum allowable size for the access transistors.

The CMOS inverter shown in Figure below has VDD = 1.8 V and is fabricated in a 0.18 μm process for which μn = 4 μp, μnCox = 400 μA/V2, and Vtn = −Vtp = 0.4 V. For this problem, neglect the Early effect. Both QN and QP use the minimum channel length allowed. For QN, W/L = 1.5. Find the width that QP must have in order for the inverter switching to occur at vI = 0.9 V. [15 points] (Hint: As vI = VDD/2, QN and QP are matched)
