Title:
READOUT OF ARRAY-BASED ANALOG DATA IN SEMICONDUCTOR-BASED DEVICES
Document Type and Number:
WIPO Patent Application WO2002082461
Kind Code:
A3
Abstract:
Systems and techniques to readout array-based analog data with reduced power requirements and reduced fixed pattern noise. An image sensor on an integrated circuit may include a sensor array to provide array-based analog data, a parallel sampling circuitry to receive the array-based analog data in parallel, a pipelined amplification circuitry to serially amplify the received array-based analog data, and an analog-to-digital converter to convert the amplified array-based analog data into digital data.
