Abstract
This work presents an area-efficient, low-power, high data rate low voltage differential signal (LVDS) transmitter and receiver with signal quality enhancing techniques. The proposed common mode feedback scheme significantly reduces the size of the LVDS transmitter by eliminating the use of area consuming passive resistor and capacitor used for close loop stability compensation. A preemphasis technique has been introduced to enhance the transmitter output’s signal quality without significantly increasing the power draw. On the receiver part, an equalization technique has also been introduced to further enhance signal quality, increases data rate and improved jitter with relatively low power consumption. The LVDS transmitter consumes 5.4 mA of current while driving an external 100 ohm resistor with an output voltage swing of 440 mV. The chip consumes an area of 0.044 mm2. This LVDS receiver has an input common mode range from 0.1 to 1.6 V. It consumes 34 mW of power with a maximum data rate of 2 Gbps. It consumes an area of 0.147 mm2 a jitter of 11.74 ps rms. A test chip is implemented using 0.18 μm CMOS process.
