ABSTRACT:
There is provided a double balance type switching circuit including a switching control signal generator; a first differential amplifier formed of first and second transistors; a second differential amplifier connected between the collector of the first transistor and a power supply terminal and formed of third and fourth transistors whose bases are respectively connected to the first and second output terminals of the switching control signal generator; and a third differential amplifier connected between the collector of the second transistor and the power supply terminal and formed of fifth and sixth transistors whose bases are respectively connected to the first and second output terminals of the switching control signal generator. The switching control signal generator produces from the first and second output terminals output signals whose voltage levels are different from one another and are converted between first and second levels, but during the conversion to output signals are temporarily made to have the first voltage level.
