This circuit was found in the January 1999 issue of Electronics Now magazine. The turn-on time is given by the capacitor and MOSFET and must be in accordance with the controlled load.
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...
