It is worth noting that 3XOR logic gates are not manufactured by the industry. It will be shown below how 2XOR and 3XOR elements can be synthesized from a set of standard discrete elements. Figure 1 ...

[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 ...

Figure 1: This circuit doubles the input frequency. The reference frequency in this circuit drives the input of an exclusive-OR gate (XOR gate U2) as well as the input to a delay circuit. Consisting ...
