Digital-PA: Ubiquitous from Low-to-High Power

Digital Power Amplifiers (DPAs) and RF-DACs such as the switched-capacitor power amplifier (SCPA) have been demonstrated successfully for both cellular communications and connectivity applications, such as Bluetooth and Wi-Fi. This owes to the compact size, superior linearity and energy efficiency of the topology. In this talk, I will provide background on design of SCPAs for high-power applications and make projections and provide some design examples that demonstrate their potential for low-power applications, such as in transmitters for IoT and in Quantum Computing.
