A High Speed CMOS Transmitter and Rail-to-Rail Receiver
ABSTRACT This paper presents a high speed low voltage differential signal (LVDS) interface circuit for CPU, LCD, FPGA and other fast links. In the proposed transmitter a stable reference and a common mode feedback circuit are applied into the LVDS drivers, which enable the transmitter to tolerate the variations of process, temperature and supply voltage. The proposed receiver implements a rail-to-rail amplifier architecture which allows a 1.6 Gb/s transmission. The transmitter and receiver are implemented in HJ TC 3.3 v, 0.18 plusmn CMOS technology. Transmission operations up to 1.6 Gb/s with random data patterns were demonstrated. The transmitter and receiver pad cells exhibit a power consumption of 35 mW and 6 mW respectively.
