BIDIRECTIONAL SWITCH SUBSTRATE VOLTAGE CONTROL

原文（中国語）

In one example, an apparatus comprises a bidirectional switch substrate bias circuit. The bidirectional switch substrate bias circuit comprises: a first switch coupled between a substrate bias terminal and a first switch current terminal, the first switch having a first switch control terminal; a second switch coupled between the substrate bias terminal and a second switch current terminal, the second switch having a second switch control terminal; and a control circuit having first and second inputs and first and second outputs, the first and second inputs coupled to the respective first and second switch current terminals, and the first and second outputs coupled to the respective first and second switch control terminals, the control circuit configured to, responsive to respective states of the first and second inputs, enable one of the first or second switches and disable the other one of the first or second switches.
