Unformatted text preview: So, in the figure above, nodes “n1” and “n3” would be initially charged to V DD , and nodes “n2” and “Out” would be initially discharged to Gnd (0V). Once these initial voltages have been set, no transistors drive the output until there is a rising transition at the input of an n inverter, or a falling transition at the input of a p inverter. In other words, the inverter’s output voltage is simply stored on the capacitance at its output. a) (3 pts) Please draw the VTC of an n dynamic inverter as its input is swept from 0V to V DD . Remember that the output of an n inverter is initially charged to V DD . Please also provide the values of V OH , V OL , V IH , and V IL ....
