Abstract
A system comprises a transmitter coupled to a receiver through a plurality of transmission lines, wherein the transmitter comprises a continuous time linear equalizer and a voltage mode driver. The continuous time linear equalizer comprises a differential input stage, a RC degeneration network coupled to the differential input stage and a current source coupled to the differential input stage. The continuous time linear equalizer and the voltage mode driver share a same input port and a same output port.
