Abstract
The invention discloses a low voltage differential signal (LVDS) receiver, which is realized in an integrated circuit. The LVDS receiver includes: an input stage circuit receiving a full-range common-mode voltage and converting it into a current signal; a current source circuit coupled to the input stage circuit to provide a current source; and a current mirror circuit coupled the input stage circuit and the current source circuit to provide several bias voltage signals for the current source circuit and output a voltage signal to a buffer.
