Consider the level translator (LS) driving M1 in the (stacked) inverter. What is the (vol, voh) out of the inverter?
Your answer
When the input is a (logic) "0", M1 and M2 are ON. Therefore the output is voh = vccd V. When the input is a (logic) "1", M3 and M4 are ON. Therefore the output is vol = 0V. The output answer pair is (vol, voh) = (0, vccd).
