ABSTRACT:
A low voltage differential signal detector capable of detecting low-voltage differential signals over a large common-mode voltage range. The signal detector uses two differential pairs of opposite conductivity type, coupled to each other in a self-biasing manner to detect low voltage swings in a signal over a large common-mode voltage range. Depending upon the common-mode voltage level of the signal, the low-voltage level swings will be detected by one of the differential pairs, the other of the differential pairs or both.
