Abstract
A Low Voltage Differential Signaling (LVDS) compliant receiver includes a differential amplifier having inputs and outputs. A first input coupling capacitor and second input coupling capacitor are electrically coupled to each of the first differential input and the second differential input, respectively. The receiver also includes a first and a second regenerative feedback latching mechanism, and the first regenerative feedback latching mechanism is electrically coupled between the first input coupling capacitor and the first differential output. The second regenerative feedback latching mechanism is electrically coupled between the second input coupling capacitor and the second differential output. An integrated circuit substrate includes each of the differential amplifier, the first differential input, the second differential input, the first differential output, the second differential output, the first regenerative feedback latching apparatus, and the second regenerative feedback latching apparatus are contained thereon. The first and the second input coupling capacitor are on-chip.
