摘要：
A radio-frequency switch includes a series field-effect transistor, a shunt field-effect transistor having a gate node, and shunt arm control circuitry configured to receive an internal regulator voltage and provide the internal regulator voltage to the gate node of the shunt field-effect transistor when the radio-frequency switch is in a stand-by mode of operation.
