This detector with ultra-low deviation was found in an American documentation from the 90s. Operational amplifiers are from that time. The power supply must be symmetrical.
The circuit shown enables dynamic diode testing with an oscilloscope. We found this configuration in a...
The circuit shown in the figure is quite interesting in control and alarm applications. This...
This different power control circuit with SCR was obtained from a 1967 magazine. The SCR can be...
