Pass Transistor Xor. If both inputs are false 0 low or both are true a false output results. The output node charges from 0 v dd v tn and the energy drawn from the power supply for charging the output of a pass transistor is given by c l v dd v dd v tn.
If both inputs are false 0 low or both are true a false output results. Figure below shows the implementation of xor function using pass transistors. For example pass transistor logic transmission gates makes it pretty simple.
Pass transistors require lower switching energy to charge up a node due to the reduces voltage swing.
For example pass transistor logic transmission gates makes it pretty simple. Figure below shows the implementation of xor function using pass transistors. Pass transistor logic ptl also known as transmission gate logic is based on the use of mosfets as switches rather than as inverters.
