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.
This circuit converts a resistance in the range between 1 k ohm and 1 MΩ to a signal in a...
We found this circuit in an old American documentation. The circuit is simple by making use of an...
We found this circuit for 330 MHz using PIC in the magazine Electronics Now of December 1994. The...
