We found this circuit in a Radio Electronics from the 90s. Transistors admit current equivalents, especially the power one that is not a common type today.
Obtained from a 1980s Linear Technology documentation, this circuit has a hysteresis of less than...
Found in documentation from the 1980s, this circuit makes use of discrete components of the time....
With this 1-transistor circuit we have a high input impedance and good gain. The circuit is from a...
