Abstract: The paper proposes a high-speed LVDS receiverembedded with failure-safe function，which ensures stable operation at 3 V or lower power supply when input common-mode voltage requirement（0.05 V to 2.35 V）may not be met and eliminates the protective circuit.During the Spectre simulation based on the model library of SMIC 0.18 μm CMOS technology，the circuit works stably in input common-mode voltage range and achieves a transmission rate up to 1 Gbps.
