Virtual zener circuit simplifies high voltage interface: 03/20/03  EDN-Design Ideas / This design for a photonic switch needs more than approximately 70V at the cathode of a duo-lateral optical position-sensing device. This voltage gets speedy response at longer wavelengths, such as 980 nm. The circuit uses fast transimpedance amps, "floated" at 70V. Two "virtual-zener" circuits step down the high-voltage signals for subsequent processing in a ground-referred differential-amplif.....
