Abstract: A low voltage different signaling (LVDS) includes an LVDS transmitter and an LVDS receiver. The LVDS transmitter includes a feedback compensation circuit, which adjusts and stabilizes the analog image signal to be transmitted to the LVDS receiver according to the voltage difference of the analog image signal and a base signal. The feedback compensation circuit includes a voltage-to-current converting circuit and a pair of current mirror circuits.

Abstract: A linear multiplier circuit comprises a first, a second, a third and a fourth transistor, each having a drain, a source, a gate and substantially an identity threshold voltage. Each of these four transistors operates with a fixed drain-to-source voltage applied between the drain and source, a gate-to-source voltage applied between the gate and source. The sources of the first and second transistors, and the drains of the third and fourth transistors are coupled to form the output terminal.
