Abstract
This invention provides an intermediate potential generating circuit comprising a load element of which one end is connected to a first potential supply source, a first transistor of a first conductivity type of which one end and the gate thereof are connected to the other end of the load element, a second transistor of a second conductivity type of which one end is connected to the other end of the first transistor, and the gate and the other end thereof are connected together, a constant-voltage means connected between the other end of the second transistor and a second potential supply source for causing a specific voltage drop between the ends of the contant-voltage means, a third transistor of the first conductivity type of which one end is connected to the first potential supply source, the gate is connected to a node between the load element and the first transistor, and the other end thereof is connected to an output terminal, and a fourth transistor of the second conductivity type which is connected between the output terminal and the second supply source and of which the gate is connected to a node between the second transistor and the constant-voltage means.
