Abstract

In this paper, a new design of readout integrated circuit application in short wave infrared is introduced. An amplifier of one transistor is employed in the CTIA to reduce the area of the unit cell. The output unit cell achieved CDS (correlated double sampling) and SH (sample and hold) is designed for public use of a whole line, and is outside the array. A new digital control structure of IRFPA ROIC is presented, with which the integral voltage of arbitrary contiguous or noncontiguous lines, rather than regular lines, can be selected to readout. The structure of the circuitry and the operation principle are analyzed, showing that the output dynamic range is over 2.5V, the cell capacity is more than 0.5Me^- the frame rate is 250Hz, and the linearity within working dynamic range is above 99.9 percent. This design is going to be fabricated through Chartered 0.35um double-poly-four-metal (DPFM) process technique, and the pixel occupies a 30um by 30um area.
