Because we’re using square waves and an XOR instead of an ideal mixer, we’ll also get other bizarre values like 2*155 – 200 = 110 Hz and 2*200 – 155 = 245 Hz, etc.

Alternatively, the CMOS inverter can also be used to drive a PTL circuit such as the XOR gate, providing a performance similar to that using an ideal voltage source (Fig. 5c and d).

XOR gates make nifty oscillators too, from AF to HF. PotatoSemi (yes, potato chip) makes GHz speed 7400 series equivalents. It would be fun to see what logic at such levels could make possible for RF.

The 10-kΩresistor cannot provide this current.However, using the previousXNOR configuration and anotherinverting transistor after Y, you canobtain the XOR function (Figure1b). The XOR seems to be ...

This paper designs an 8:1 multiplexer with CMOS Transmission Gate Logic (TGL) using the power gating technique, which reduces the leakage power and leakage current in active mode.
