The presented circuit makes use of a common operational amplifier that must be powered by a symmetrical source. R resistors from 10k to 1M determine the gain and compression of the signal.
We found this circuit without bounce in an Elektor from the 90s. The circuit can be used as a...
The circuit shown in the figure consists of a 200mA low voltage drop (LDO) regulator using the...
Hughes suggests this circuit in a 1968 documentation. The circuit uses old transistors that can be...
