Abstract
A differential driving circuit includes a source current source, a sink current source, an H-bridge circuit, an error detector unit and a circuit network. The H-bridge circuit is connected to the source current source and the sink current source, that has a first output terminal and a second output terminal, and that generates differential output from the first output terminal and the second output terminal. The error detector unit adjusts a common mode voltage at the first output terminal and the second output terminal of the H-bridge circuit by controlling at least one of the source current source and the sink current source. The circuit network is configured by resistors and capacitors connected to the first output terminal and the second output terminal of the H-bridge circuit.
