title = "Sense resistor-free analog power sensor for boost converter with 14.1% gain error and 9.4% offset error",
abstract = "This paper presents an analog power sensor to measure DC-DC converter output power for DC-DC voltage regulation and photo-voltaic (PV) maximum power point tracking (MPPT) applications. The proposed power sensor senses current without using a conventional series resistor, and provides power information without using additional circuits for power calculation. The proposed circuit is implemented using a switched capacitor differentiator and a voltage-To-Time converter. Compared to the resistor based sensing method that requires a current-To-voltage circuit, a gain block, two analog-To-digital converters (ADCs) and a digital signal processor (DSP), the proposed power sensor provides lower complexity, lower area and lower power consumption for MPPT PV applications. A prototype module is designed and the measured results show 14.1% gain error and 9.4% offset error in the power measurements.",
