Abstract
A low voltage differential signal (LVDS) receiver includes a first receiving unit configured to receive a reference voltage and to responsively generate a first differential signal, and a second receiving unit configured to receive a voltage developed across a variable termination resistor unit having a resistance that is adjustable based on a resistance control code in response to a reference current, and to responsively generate a second differential signal. The LVDS receiver further includes a comparing unit configured to compare the first differential signal with the second differential signal and to responsively generate a counter control signal. The LVDS receiver further includes an up/down counter configured to adjust the resistance control code in response to the counter control signal. The up/down counter is further configured to provide the resistance control code to the variable termination resistor unit. Corresponding methods are also disclosed.
