A switch circuit includes a pair of metal oxide semiconductor (MOS) switches and an adjusting unit. Each of the MOS switches has an input terminal and an output terminal. The MOS switches receive a pair of differential input voltages at the input terminals thereof, and output a pair of differential output voltages at the output terminals thereof when the MOS switches conduct. The adjusting unit changes a difference between common mode levels of the input terminals and the output terminals of the MOS switches so as to adjust linearity of differential mode resistances of the MOS switches.
