    • Envelope-tracking control techniques are disclosed for highly-efficient radio frequency (RF) power amplifiers. In some cases, a III-V semiconductor material (e.g., GaN or other group III material-nitride (III-N) compounds) MOSFET including a high-k gate dielectric may be used to achieve such highly-efficient RF power amplifiers. The use of a high-k gate dielectric can help to ensure low gate leakage and provide high input impedance for RF power amplifiers. Such high input impedance enables the use of envelope-tracking control techniques that include gate voltage (Vg) modulation of the III-V MOSFET used for the RF power amplifier. In such cases, being able to modulate Vg of the RF power amplifier using, for example, a voltage regulator, can result in double-digit percentage gains in power-added efficiency (PAE). In some instances, the techniques may simultaneously utilize envelope-tracking control techniques that include drain voltage (Vd) modulation of the III-V MOSFET used for the RF power amplifier.

Either of the CMOS or III-N portions can be native to the underlying substrate to some degree.
