This configuration can be implemented with equivalent operations. The circuit is from the 1990 Motorola Linear Databook. The voltage gain is 100 times.
This circuit uses only passive components and the instrument can be a microammeter or the lowest...
This is the traditional configuration of a high-pass filter with an operational amplifier, such as...
The LM386 is an audio amplifier, but it can be used as a good oscillator with a positive feedback...
