Both the operational amplifier and the diodes admit equivalents in this circuit suggested by National Semiconductor. The power source must be symmetrical, and the circuit curve resembles an ideal diode.
This amplifier uses common transistors in a phase inverter configuration. Transistors must be...
This is the same amplifier circuit as the previous circuit adapted to operate with a single...
In fact, this 1994 circuit uses a scale of LEDs to indicate the pulse rate applied to its input....
