Abstract
The invention provides a Low-voltage Differential Signaling (LVDS) receiver circuit that comprises a folded-cascode operational transconductance amplifier (OTA) that includes a pair of input branches and a pair of output branches. The pair of input branches of the folded-cascode OTA includes a p-channel metal-oxide semiconductor (PMOS) input transistor pair connected to a first supply voltage domain. The pair of output branches includes an output circuit connected to a second supply voltage domain. The LVDS receiver circuit further includes a common-mode feedback circuit connected to the pair of output branches of the folded-cascode OTA that controls the second supply voltage domain. The LVDS receiver circuit further includes a regenerative buffer circuit connected to the pair of output branches of the folded-cascode OTA and an output generated from the pair of output branches of the folded-cascode OTA directly operates the regenerative buffer circuit to produce a distortion-free output signal.
