| 摘要 | This document discusses, among other things, a signal switch circuit including a first field effect transistor (FET) configured to couple a first node to a second node in an on-state and a charge pump circuit configured to provide a first supply voltage to control the FET, wherein a reference voltage of the charge pump circuit is coupled to a well of the FET to maintain a constant gate to source voltage of the FET during the on-state. | ||

| 主权项 | 1. A switch circuit defining an on-state and an off-state, the switch circuit, when in an on-state, couples a first node to a second node and, when in the off-state, isolates the first node from the second node, the switch circuit comprising: a first field effect transistor (FET) configured to couple the first node to the second node in the on-state; a charge pump configured to provide a first supply voltage to control the FET; and wherein a reference voltage of the charge pump is coupled to a well of the FET to maintain a constant gate to source voltage of the FET during the on-state. | ||
