To overcome the limited in-pixel resolution of such DROICs, the concept of error shaping is introduced in pulse frequency modulation (PFM)-based pixels. Multiple integration operations are performed in a single frame and the residue charge from each integration phase is retained and injected into the next charge packet. This over-integration routine provides a high pass noise transfer function (NTF) equivalent to what is obtained in a first order sigma delta modulator. The concise structure of a PFM analog-to-digital converter (ADC) lends itself well to such an operation inside the pixel, while consuming low power. Along with a theoretical analysis of the technique, a prototype based on a 16 x 16 array and sinc decimation filters is developed to demonstrate the performance of the proposed DROIC. With an in-pixel resolution of 5 bits and over-integration ratio (OIR) of 128, 395 noise electrons are demonstrated at full-well fill from the test array fabricated in a 90 nm bulk-CMOS process.</subfield> </datafield> </record>
