Abstract:
1. An analog switch circuit comprising: a first field-effect transistor, a source of which is coupled to a first switch terminal, and a drain of which is coupled to a second switch terminal; a first capacitance to store electric charge; a second capacitance to store electric charge; a first switching element that is coupled between the direct current voltage node and a first terminal of the first capacitance; a second switching element that is coupled between the reference potential node and a second terminal of the first capacitance; a third switching element that is coupled between the first terminal of the first capacitance and a first terminal of the second capacitance; a fourth switching element that is coupled between the second terminal of the first capacitance and a second terminal of the second capacitance; a fifth switching element that is coupled between the first terminal of the second capacitance and a gate of the first field-effect transistor; and a sixth switching element that is coupled between the second terminal of the second capacitance and the source of the first field-effect transistor.
