An input buffer circuit that receives differential signals includes a first resistive path circuit, a second resistive path circuit and a feedback circuit. The first resistive path circuit may generate a first common mode voltage from the differential signals. The feedback circuit is coupled to the first resistive path circuit. The feedback circuit receives the first common mode voltage as an input. The second resistive path circuit includes a transistor circuit and a resistor formed in a serial circuit configuration. The second resistive path circuit may generate a second common mode voltage on a node formed between the transistor circuit and the resistor by controlling activation of the transistor circuit using outputs from the feedback circuit. The first common mode voltage may be substantially identical to the second common mode voltage.
