A Quadrature Switched Capacitor Power Amplifier

IEEE Journal of Solid-State Circuits, 2016
This paper presents an all-digital class-G quadrature switched-capacitor power amplifier (Q-SCPA) implemented in 65 nm CMOS. It combines in-phase ( I ) and quadrature ( Q ) signals on a shared capacitor array. The I / Q signals are digitally weighted and combined in the charge domain.

Calculation of Temperature Field in Power Capacitor

IEEE Transactions on Industrial Electronics, 2015
The operating temperature of a power capacitor has an effect on its service life directly. A 500-kvar power capacitor is taken as the research object. The capacitor fever produced by internal dielectric loss is considered under the running condition of 55 $^{\circ}\hbox{C} $ .
