The operational amplifier used in this circuit is uncommon nowadays. We obtained this circuit from documentation from the 1980s, but it can be adapted to use more modern equivalents.
This circuit shows how to control an astable configuration using the 555 IC. The control signal is...
Found in the August 1994 issue of Electronics Now, this CMOS circuit uses the 4046, which is...
This is the transmitter for the previous circuit. We found it in a 90s Electronics Now. The...
