This digital thermometer circuit diagram uses a common 1N4148 diode as the temperature sensor. The temperature coefficient of the diode, -2 mV/°C is exploited for this application to create an ...

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

The ideality factor is typically constant for a given diode, being 1.9 for the 1N4148 diode [1]. Observed circuit predictability is better for silicon diodes than germanium diodes. In the last ...
