Abstract
A pyroelectric generator may be included in the same semiconductor device as a radio frequency (RF) switch (e.g., a phase-change material (PCM) RF switch and/or other types of RF switch). The pyroelectric generator includes a pyroelectric material layer between two electrodes. The pyroelectric generator is configured to scavenge thermal energy that is generated during the operation of the RF switch, and to convert the thermal energy into electrical energy that may be stored and reused.
