The Fig. 1 example includes LED loads D1 + D2, D3 + D4, D5 + D6 and a power-supply output voltage, with a constant output current, providing the circuit input voltage (V IN).

A perovskite photo diode that becomes a viable LED when its bias is reversed has been created at Linköping University in Sweden, allowing bidirectional communication between two identical devices. “We ...

Oh, my! I love it, especially “LED–transistor” logic! That idea, visible diodes, should be part of every course in electronics. It’s a wonderful example of “thinking out of the box ...

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