Here, high impedance (or Z floating) is possible as an output if pull-up and pull-down networks are both OFF.Secondly CMOS has the huge advantage of very low power consumption when not switching, because the gate of a CMOS transistor is essentially a capacitor and passes no DC current and only one of the transistors is switched on at a time so there is no significant DC current by that path either.The digital buffer is the logic gate opposite of an inverter (Not Gate) we look at in the previous tutorial where we saw that the NOT gates output state is the complement, opposite or inverse of its input signal. ... Most CMOS IC’s operate over a range of different supply voltages, but its the individual inputs that do the switching, so at 5 ...Fan-out. In digital electronics, the fan-out is the number of gate inputs driven by the output of another single logic gate. In most designs, logic gates are connected to form more complex circuits. While no logic gate input can be fed by more than one output at a time without causing contention, it is common for one output to be connected to ...
Question 4. The simplest type of digital logic circuit is an inverter, also called an inverting buffer, or NOT gate.
