This circuit was found in a 90s Radio Electronics. MOSFETs must have excellent heat sinks and heat and the board layout carefully planned to withstand high currents.
More and more supercapacitors are being used as supplementary sources of energy in several...
Varactor diodes are our varicaps of today. This circuit for switching signals in an RF circuit was found...
In this circuit the output current is limited by R3. For a 300 mA current, R3 must have 12 Ω. For...
