Abstract:
A single-ended to differential conversion circuit for converting an input signal into a pair of differential signals is provided. An amplifier includes an inverting input terminal, a non-inverting input terminal for receiving a reference signal, and an output terminal. A first resistor is coupled between the inverting input terminal and the output terminal of the amplifier. A second resistor is coupled to the inverting input terminal of the amplifier. The third resistor is coupled to the output terminal of the amplifier. The resistor string is coupled between the output terminal of the amplifier and the second resistor, and includes a fourth resistor and a fifth resistor connected in series. A signal of the pair of differential signals is provided via the third resistor, and another signal of the pair of differential signals is provided via the resistor string.
