This circuit from the 80's makes use of two transconductance operationals of the time. Modern equivalents can be used. The circuit does not need to be powered by a symmetrical source.
The purpose of this interesting circuit found in a 1977 documentation is to complete the last...
This circuit allows to drive a triac with high power AC load from a CMOS output or directly from a...
This circuit was obtained in a documentation from the 80's. However, using TTL it is still modern,...
