Title: Semiconductor integrated circuit device
Inventor: KONDO MASAO
IPC: H01L27/06
Filed: 2009-07-03
Abstract: PROBLEM TO BE SOLVED: To significantly reduce harmonic distortion while using SOI MOSFETs (Silicon On Insulator Metal Oxide Semiconductor Field Effect Transistors) as transistors for switching of an antenna switch.SOLUTION: Capacitance elements 54-58 are respectively added to either the respective drains or gates of transistors 44-48 constituting a through MOSFET group 13 of reception branch of an antenna switch. This makes the voltage amplitude between source and gate and that between drain and gate different from each other. As a result, the voltage dependence of source-drain parasitic capacitance becomes asymmetric with respect to the polarity of voltage. This asymmetry property produces signal distortion having similar asymmetry property. Therefore, by setting it to have the same amplitude as that of second-harmonic waves arising from the voltage dependence of substrate capacitance and a phase opposite to that of the same, second-order harmonic distortion can be canceled out and thus second-order harmonic distortion can be reduced.
