Abstract
Embodiments of the disclosure are drawn to apparatuses a hybrid switched capacitor array power amplifier (H-SCPA). The H-SCPA may have an array of storage elements divided into sub-arrays. A first sub-array may be configured to receive a delta sigma modulated (DSM) signal. A second sub-array may be configured to receive a Nyquist-rate signal. The H-SCPA may provide an output based on the received DSM and Nyquist-rate signals. The first sub-array and second sub-array may have different architectures. The DSM signal may represent the least significant bits of the signal and the Nyquist-rate signal may represent the most significant bits of the signal.
