A differential to single ended converting circuit includes a transconductance circuit having input terminals for receiving differential input voltages and having a first current output terminal for outputting a first current and a second current output terminal for outputting a second current; an offset cancellation circuit having a first controllable current source connected to the first current output terminal and a second controllable current source connected to the second current output terminal; a first transimpedance circuit having an input terminal connected to the first current output terminal and an output terminal for outputting a first voltage; a second transimpedance circuit having an input terminal connected to the second current output terminal and an output terminal for outputting a second voltage; and a first inverter having an input terminal connected to the output terminal of the first transimpedance circuit and an output terminal for outputting a first single ended output voltage.
