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 high-gain circuit uses junction FETs (JFETs) and must be powered by somewhat high voltages. The...
This circuit counts 1 per second, displaying the value in binary. The circuit is TTL and must be...
Critical components of this project are the Geiger tube and the 300V battery. The battery can be...
