Abstract:
A current switching type switch circuit comprising:a current source connected between a first power source line and a first node;a first transistor connected between said first node and a second node, an non-inverting clock signal being supplied to a control terminal of said first transistor;a second transistor connected between said first node and a third node, an inverting clock signal being supplied to a control terminal or said second transistor;a third transistor being connected between said second node and a second power source line, a control terminal of said third transistor connected to said second nods;a fourth transistor connected between a third node and said second power source line, a control terminal of said fourth transistor being connected to said third node;a fifth transistor connected between said second power source line and a fourth node, a control terminal of said fifth transistor being connected to said second node, and a first load circuit being connected between said fourth node and said first power source line; anda sixth transistor connected between said second power source line and a fifth node, a control terminal of said sixth transistor being connected to said third node, a second load circuit being connected between said fifth node and said first power source line, said first and second load circuits being complimentarily driven in response to said non-inverting and inverting clock signals, respectively.
