The circuit in the figure uses two operational amplifiers: an LM101A and an LM102. Diodes admit equivalents and resistors do not have to be accurate. The power supply must be symmetrical.
We found this circuit in Radio Electronics magazine from September 1959. The circuit has different...
The LM109 is not a current integrated circuit, having been manufactured by many semiconductor...
This frequency divider circuit that generates a ladder-shaped signal was found in the June 1968...
