Unformatted text preview: has to make a transition in order to achieve this maximum propagation delay. Consider the effect of the capacitances at the internal nodes. (provide only a qualitative discussion, without going into exact equations) Question 2: Pass transistor Logic a. Determine the truth table for the circuit. What logic function does it implement? (Assume the PMOS device is weak) b. Assuming 0 and 2.5V inputs, size the PMOS transistor to achieve a V OL of 0.3V. c. If the PMOS were removed, would the circuit still function correctly? Does the PMOS transistor serve any useful purpose? EECS170D Fall 07...
