Wireless circuitry is provided that includes radio-frequency amplifier circuitry. The amplifier circuitry can include multiple capacitors, each of which has a first terminal coupled to an antenna and a second terminal. The amplifier circuitry can include at least one capacitor switching circuit coupled to the second terminal of one of the capacitors. The capacitor switching circuit can include a pull-up transistor configured to receive a first voltage signal and a cascode transistor coupled between the pull-up transistor and an output of the capacitor switching circuit. The cascode transistor can be configured to receive a second voltage signal that toggles while the at least one capacitor switching circuit is configured to operate in at least a plurality of swing modes.
