This crowbar protection circuit for non-regulators blows the fuse when the load voltage exceeds a certain value. The configuration with component values can be seen in the previous circuit.
Details of the coil of this two-transistor generative receiver were not given. We found it in a...
This very high input impedance circuit is suggested by Texas Instruments. The circuit can be...
This circuit from an 80's publication also features low input capacitance. FET can be a modern...
