Monolithically-integrated circuit, system, electronic device and method

A system comprising:

• a plurality of monolithically-integrated circuits, each of the plurality of monolithically-integrated circuits comprising:
• a radio frequency (RF) switch,
• a first terminal configured to receive a first reference voltage signal for an ON-state of the RF switch,
• a second terminal configured to receive a second reference voltage signal for an OFF-state of the RF switch,
• decoder circuitry configured to decode a control sequence encoded in the first reference voltage signal or the second reference voltage signal, wherein the control sequence is configured to control a switch state of the RF switch, and
• level-shifter circuitry configured to adjust, based on the control sequence, the switch state of the RF switch by selectively level-shifting a voltage level of one of the first reference voltage signal or the second reference voltage signal and supplying the level-shifted first reference voltage signal or the level-shifted second reference voltage signal to the RF switch;
• and
• power management circuitry configured to supply the first reference voltage signal for the plurality of monolithically-integrated circuits.

A method for operating a radio frequency, RF, switch of a monolithically-integrated circuit, the method comprising:

• receiving, at a first terminal of the monolithically-integrated circuit, a first reference voltage signal for an ON-state of the RF switch;
• receiving, at a second terminal of the monolithically-integrated circuit, a second reference voltage signal for an OFF-state of the RF switch;
• decoding a control sequence encoded in at least one of the first and the second voltage signals for controlling a switch state of the RF switch;
• and
• adjusting, based on the control sequence, the switch state of the RF switch by selectively level-shifting a voltage level of one of the first and the second reference voltage signals and supplying the level-shifted first reference voltage signal or the level-shifted second reference voltage signal to the RF switch.
