1. (10 points) For the logic circuit below, assume that Vpp : 2.5V, Vn 0.5 V, Vtp : -0.4V, kL -ZO pA I V', k!, I20 pA lV', Vosarp - - 1 V, and W L of all the nMOS transistors is 6. (a) (zpoints) Determine tlre logic function implemented. (b) (3 points) What is thb voltage level at node z if A 0 and B 7? This voltage level causes static powerdissipation. Explain why. (c) (2 points) Determine a remedy to the static power dissipation problem in part (b) using a single pMOS transistor. Draw the fix directly in the figure. (d) (3 points) Now set A B 1. Determine the size (WIL) of the pMOS transistor added to the circuit in part (c) so thatVu for the inverter input is less than Vr"12. ht {= Te+ Ae Y= T: AB+T{ f xruon) Cb) wh€n A=o and B= {" .
