A 3MPixel Multi-Aperture Image Sensor with 0.7μm Pixels in 0.11μm CMOS

Abstract

In this paper we describe the first complete MA-imager chip comprising a 166x76 array of 16x16, 0.7mum pixel FT-CCD apertures, per-column ADCs, control logic and chip readout circuits fabricated in 0.11mum CMOS technology. The aperture control buses are globally connected to the FT-CCDs. The RS signal and the decoded ROW bus are used to address the readout circuits for each row of FT-CCDs. The MUX blocks contain column bias circuitry, inputs for external testing of the ADC and support for analog pixel readout through AOUT. The ADCs share an output bus that is decoded by COL and buffered for digital readout.
