Abstract: In order to provide both common mode voltage and current source to Low-Voltage Differential Signaling (LVDS) driver, a novel structure of band gap reference is proposed in this work to provide both voltage reference and current reference with a high performance of temperature characterizes. Bipolar transistors are used in proposed circuit to generate ideal temperature coefficients. The DC simulation shows the voltage temperature coefficient is 17.4 ppm/℃ and current temperature coefficient is 63.3ppm/℃. By using proposed band gap reference, the stability of LVDS can be significantly improved.
