PROBLEM TO BE SOLVED: To ensure a stable operation under a low power supply voltage by positively using a reverse short channel effect in a ratio circuit. SOLUTION: In this ratio circuit, an N channel MOS transistor 12 of one CMOS circuit 10 constitutes a driving element, and a P channel MOS transistor 18 of the other CMOS circuit 16 constitutes a load element. The drain terminals of those driving side N channel MOS transistor 12 and load side P channel MOS transistor 16 are electrically connected through a transfer gate 22 consisting of an N channel MOS transistor with each other. The driving side N channel MOS transistor is provided with a single channel CHa developing a reverse short channel effect. The load side MOS transistor 18 is provided with plural, for example, two cascade-connected channels CHb1 and CHb2 both developing reverse short channel effects.
