Similarly, when a high voltage (15V) is applied at the gate terminal, the MOSFET operates in the saturated mode, and a low impedance is present between the drain and source terminals of the MOSFET.

For example, only two transistors are needed for both the OR and AND gates, whereas a total of six transistors are needed in the corresponding conventional CMOS circuit 27,28.

[IMSAI Guy] grabbed an obsolete XOR gate and tried a classic circuit to turn it into a frequency doubler.Of course, being an old part, it won’t work at very high frequencies, but the circuit is ...
