Abstract
A signal detector circuit and digital signal receiver implementing the same. In one embodiment the digital signal receiver includes a switch point detector having a detector output and including a transistor array comprising one or more pull-up branches and one or more pull-down branches. A switch point control circuit is coupled to the switch point detector. The switch point control circuit generates branch enable signals for selectively enabling or disabling said one or more pull-up branches and said one or more pull-down branches in a detector output polarity dependent manner.
