PURPOSE:To stabilize the threshold characteristic of a MOS transistor (TR) by applying a power voltage of the pre-stage of a back gate of a CMOS TR receiving an output of the circuit of pre-stage different in power voltage. CONSTITUTION:The operating power voltage of the pre-stage circuit is applied to a linear circuit section 2 having a larger operating power voltage than that of the CMOS circuit 1 and a back gate of a CMOS TR M1 of an interface circuit section 3 interfacing with the CMOS circuit 1. Thus, the production of the polarization of the residual component is prevented to a gate insulation film of a MOS TR and the threshold characteristic of the MOS TR is made stable to stabilize the input operation. |
