Analog switches and methods for controlling analog switches
An analog switch may be maintained reliably in an off state. The switch comprises: a P-type first transistor having a source, a drain and a gate, a N-type second transistor having a source, a drain and a gate, and a switch control circuit to drive the gates of the first and second transistors. The d...

Summary: | An analog switch may be maintained reliably in an off state. The switch comprises: a P-type first transistor having a source, a drain and a gate, a N-type second transistor having a source, a drain and a gate, and a switch control circuit to drive the gates of the first and second transistors. The drain of the first transistor and the source of the second transistor are connected at a first node, and the source of the first transistor and the drain of the second transistor are connected at a second node. When the voltage at the first or second nodes falls outside of a supply voltage range of the switch control circuit, the switch control circuit is operable, in response to a signal to make the switch high impedance, by adjusting the gate voltages of the first transistor and the second transistor. |
