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 configuration was found in a 1976 publication. The outputs of the logic circuits are applied to...
With this circuit it is possible to measure frequencies up to about 500 kHz using a common...
The very high-input impedance of the CMOS gate allows this kind of device to be used as a...
