and the basic logic gates, including OR, AND and XOR, are realised with ideal high and low logic states. By incorporating a CMOS inverter with a gain much greater than one in the PTL circuits, PTL ...

[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 ...

Logic Noise is an exploration of building raw synthesizers with CMOS ... gates and you’re nearly done. Connect the final two XOR outs through resistors to the output. As with the cowbell circuit ...
