We found this circuit in a Radio Electronics magazine from November 1976. The clock frequency is divided by 10 and the maximum value depends on the integrated circuits used.
Other operational amplifiers of the same series can be used on this circuit found in Motorola's Linear...
This circuit is designed to force a current greater than that of the fuse onto the transistor in...
This circuit amplifies signals from 0.5 Hz to 300 kHz. We found it in an old documentation. Equivalent...
