Analog switch circuit for wide frequency band |
摘要 |
An analog switch circuit that includes 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 storing electric charge; a second capacitance storing electric charge; a first switch circuit that couples the first capacitance between a direct current voltage node and a reference potential node; a second switch circuit that couples the first capacitance and the second capacitance in parallel; and a third switch circuit that couples the second capacitance between a gate and the source of the first field-effect transistor. |
