Abstract: Methods and apparatuses are provided in which a level shifter of a digital control circuit for a switchable voltage supply circuit shifts a domain level of a first input. A first inverter of the digital control circuit inverts output of the first level shifter to output a first gain voltage to turn on a first switch of the switchable voltage supply circuit or output a second gain voltage to turn off the first switch. A second inverter of the digital control circuit inverts a second input to output a third gain voltage to turn on a second switch of the switchable voltage supply circuit or output a fourth gain voltage to turn off the second switch. The first gain voltage is greater than the third gain voltage.

Abstract: A single-pole single-throw (SPST) radio frequency (RF) switch is provided that includes one or more switches stacked in series, and a first capacitor disposed at an input side of the SPST RF switch, in series, before the one or more switches. The SPST RF switch also includes a second capacitor disposed, in parallel, across the one or more switches, and an inductor disposed at an output side of the SPST RF switch, in series, after the one or more switches.
