Non-linear Photo Isolator and Its Response Maintaining Function
Guo Wei · Bandaoti guangdian · 2002
A new type of photo isolator has been developed by packing light emitting devices with silicon photo negative resistance devices face to face to realize electrical isolation. With the bistability and self locking of the silicon photo negative resistance devices, these non linear photoisolators exhibit response maintaining function for the input signal. The demonstration of response maintaining function on PDUBAT is made experimentally and the realization of response maintaining function on PLBT is proposed
