Abstract:As the Internet of Things (IoT) is rapidly integrated into our daily life, the demand for high performance readout integrated circuit (ROIC) design for sensor arrays is boosting. This paper presents a low power, low noise ROIC with 14-bit column-parallel extended counting (EC) ADCs for sensor arrays targeting the IoT applications. The proposed EC-ADC adopts a pseudodifferential architecture to cancel even-order nonlinearity. The analog front-end is a
