It is similar to the standard JFET circuit but has a supplementary bipolar transistor that shunts most negative-going currents when the JFET is on. R 2 prevents the gate of Q 1 from floating, and R 3 ...

The value of R1 is determined by the maximum laser current required (in this case, 250 mA), adjusted by the laser diode's typical forward voltage of 2.0 V as given on the datasheet. Solving for R1 ...

The input impedance of the detector is around 300kO, which doesn’t appreciably load the source. The diode is operated with a slight forward bias so a regular silicon signal diode (e.g., 1N914) can be ...

A superconducting diode bridge composed of four superconducting diodes efficiently converts AC to DC at cryogenic temperatures, achieving rectification efficiencies up to 42% ± 5%.

A transient-voltage-suppression diode macromodeloffers greater accuracy than a standarddiode SPICE model. SPICE circuit simulations are a powerful design tool to analyze a system's immunity ...
