This regulator or voltage reference consists of a variable zener diode. We found it in the June 1984 issue of Radio Electronics magazine. The output current is low.
This circuit has the transistor chosen according to the maximum current desired at the output. Unlike...
We found this configuration with CMOS-compatible output in the 1994 National Semiconductor Linear...
This very low frequency amplifier has a gain of 1,000 and was found in a 1967 documentation. The circuit is...
