This circuit uses a dual-gate MOSFET, a rare component today. We found it in American documentation from the 1980s. The rest of the components are common.
Found in a 90s Silicon Chip documentation, this circuit provides a current of 3 A and the voltages...
We found this circuit in a Japanese publication in 1967. The circuit consists of a 15 W audio...
This is a bridge for the measurement of low value resistances and high values too. The circuit...
