信号输出电路以及半导体集成电路

Abstract

本发明涉及输出对输入信号为基准电压不同的信号的信号输出电路,其目的是提供使以不同的基准电压被驱动的多个电路可以容易地结合的信号输出电路。本发明是一种将从以第1基准电压(V01)作为基准被驱动的第1电路(112)来的信号输出到以第2基准电压(V02)作为基准被驱动的第2电路(113)的信号输出电路,其特征在于,具有:第1控制电路(121、122、Q11、R11、Q12),其根据来自第1电路(112)的输出信号对第1基准电压(V01)引入电流,根据引入的电流向第2电路(113)提供信号;和第2控制电路(Q13、R12),其由第2电路(113)对第2基准电压(V02)引入电流。
A signal output circuit is disclosed that supplies a signal from a first circuit that is driven based on a first reference voltage to a second circuit that is driven based on a second reference voltage. The signal output circuit includes a first control circuit that draws a current to the first reference voltage according to an output signal from the first circuit and supplies a signal to the second circuit according to the drawn current, and a second control circuit that draws a current from the second circuit to the second reference voltage.
