A 6.25Gb/s low voltage differential signal(LVDS)transmitter with pre-emphasis was designed based on SMIC 40 nm CMOS technology.The low voltage differential driver used dual op amp closed-loop feedback control structure to stabilize the swing of output signal.The pre-emphasis circuit used pulse-current boosting structure,which emphasized output signal to overcome high frequency signal loss during transmission.This transmitter could output a low voltage differential signal with the swing of 300 mV and the rate of 6.25Gb/s.The pre-emphasis radio was 3.5dB.The power consumption was 7.1mW.This transmitter was applicable for rapid IO PHY circuit.
