BAND-GAP BIAS CONTROLLING CIRCUIT AND SEMICONDUCTOR INTEGRATED CIRCUIT WITH THE SAME

摘要

A band-gap bias controlling circuit and a semiconductor integrated circuit including the same are provided to stabilize a bias voltage at high speed by controlling the switching of a voltage level forming a node using a band-gap voltage. A band-gap bias controlling circuit includes first and second nodes(N1,N2), first and second voltage generators(110,120), and a switching unit(130). The first voltage generator generates a positive bias voltage to the first node according to a sleep mode signal. The second voltage generator generates a negative bias voltage to the second node according to the sleep mode signal. The switching unit switches the first and second nodes according to the sleep mode signal and a band-gap voltage.
