Unformatted text preview: transistors. (b). Size your transistors such that the circuit has the same worst case rise and fall times. You can assume that the minimum channel length is used for both N and P mos transistors, which is the same for both types of transistors. In addition, the mobility of holes is half of that of electrons and other relevant device parameters are the same for N and P type transistors. Notice that in addition to having the balanced worst case rise and fall times, you should also try to balance the signal delays between different conducting paths in your circuit so as to minimize the chip area. (c). Draw the schematic of the pseudo-NMOS version of your design....
