Indicated on an 80's Radio Electronics, this circuit provides at its output a voltage that is the peak value of the input voltage. The supply voltage must be higher than the expected peak.
This amplifier uses a 1975 integrated circuit, which is uncommon today. The circuit has a gain of 30...
Using junction FETs, a configurable configuration is achieved for very low frequencies. FETs can...
This 2-terminal regulator was obtained from a 1990s National Semiconductor manual. The components admit...
