“…As shown, the pre-emphasis driver is not only able to shorten the rise time but also improves the amplitude of the output signal. In addition, a pre-emphasis driver with a simple pulse-width modulation (PWM) technique [26,27] is used in the transmitter to enhance signal integrity. A simplistic circuit of this pre-emphasis driver is presented in Figure 8.…”

This paper presents a 2.5 Gbps 10-lane low-power low voltage differential signaling (LVDS) transceiver for a high-speed serial interface. In the transmitter, a complementary MOS H-bridge output driver with a common mode feedback (CMFB) circuit was used to achieve a stipulated common mode voltage over process, voltage and temperature (PVT) variations. The receiver was composed of a pre-stage common mode voltage shifter and a rail-to-rail comparator. The common mode voltage shifter with an error amplifier shifted the common mode voltage of the input signal to the required range, thereby the following rail-to-rail comparator obtained the maximum transconductance to recover the signal. The chip was fabricated using SMIC 28 nm CMOS technology, and had an area of 1.46 mm2. The measured results showed that the output swing of the transmitter was around 350 mV, with a root-mean-square (RMS) jitter of 3.65 ps@2.5 Gbps, and the power consumption of each lane was 16.51 mW under a 1.8 V power supply.
