ABSTRACT:
A current-mode four-quadrant analog multiplier is provided, which is constructed based on CMOS (complementary metal-oxide semiconductor) technology, capable of generating an output current signal which is proportional in magnitude to the product of two input current signals. This current-mode analog multiplier is designed based on the translinear circuit principle. The current-mode analog multiplier has high precision, wide current dynamic range, and is insensitive to temperature and process, suitable for use in VLSI implementation of many analog circuits and systems, such as fuzzy logic controllers and analog neural networks.
