摘　　要：A multi-standard compatible transmitter with pre-emphasis for high speed serial links is presented. Based on the comparison between voltage mode（VM） and current mode（CM） output driver architectures,a low power CM output driver with reverse scaling and bias current filtering technique is proposed.A 2-tap pre-emphasis filter is used to reduce the intersymbol interference caused by the low-pass channel,and a high speed,low power combined serializer is implemented to convert 10 bit parallel data into a serial data stream.The whole transmitter is fabricated in 65 nm 1.2 V/2.5 V CMOS technology.It provides an eye height greater than 800 mV for data rates of both 2.5 Gb/s and 5 Gb/s.The output root mean square jitter of the transmitter at 5 Gb/s is only 9.94 ps without pre-emphasis.The transmitter consumes 41.2 mA at 5 Gb/s and occupies only 240×140μm^2.A multi-standard compatible transmitter with pre-emphasis for high speed serial links is presented.
