Design of a TYPE-I M-LVDS receiver IC based on TIA/EIA-899 standard

We propose an implementation scheme for a TYPE-I M-LVDS receiver based on TIA/EIA-899 standard.A novel common-mode voltage shift circuit is designed to realize an input common-mode range that is beyond the rail of the power voltage,which can simplify the post stage circuit,thus saving area and power consumption.The pre-amplifier in the receiver can provide a fixed magnification for input signals,and the hysteresis comparator brings hysteresis effect to the system.The chip is fabricated in GSMC 0.18μm 1P6 M CMOS technology,and the test results indicate that the receiver has an input common-mod range of-1.4V~3.8V,a signaling rate greater than 250 Mbps,and a typical hysteresis voltage is 28 mV.
