ABSTRACT:
A constant current source is connected to a first node that connects on the one hand to a predetermined potential via a first switching transistor with a control electrode thereof connected to a signal input terminal, a second node, and a resistive conduction member, and on the other hand to a current output terminal via a second switching transistor with a control electrode thereof connected to the second node to constitute a current switching circuit operable without an external reference bias and with a reduced number of components.
