PURPOSE:To enhance the integrity of a MOS analog switch by forming an offset voltage cancelling MOS transistor in the drain or source of a MOS switching element. CONSTITUTION:An offset cancelling MOS transistor 9 is associated within the drain 8 of a MOS switching element having a gate 6, a source 7 and a drain 8. Thus, the integrity of an LSI employing an analog MOS switch such as a subscriber's circuit high withstand voltage MOS switch or a CODEC MOS switch or the like can be enhanced. |
