Summary

XOR circuit using diodes from EDNs Design Ideas.


Description

Run the time domain simulation to see the XOR in action. The inputs are offset square waves to demonstrate the XOR works as expected. Note in the plots that when A=B Y is logic low and when A != B Y is logic high. In a real application A and B would be driven by CMOS logic, and Y is can drive a CMOS digital input.
