In the figure we have the way to obtain the Exclusive-OR function with 1 transistor. The circuit is from a 1964 Electronic Design. The transistor can be any general purpose PNP.
We present a circuit formed by six voltage comparators. Each comparator will analyze the voltage...
This circuit can generate time base signals from 5 to 1500 Hz. We find it in a documentation about old neon...
In this circuit the CA3140, an operational amplifier, is used as a comparator with the zener diode...
