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 first circuit, shown in the figure, generates a stepped signal whose frequency depends on the...
This differential amplifier, found in a 1964 Electronic Design, has a gain of 30. The setting can be...
The purpose of this circuit is to control the high and low light of a car, detecting when a...
