Infrared (IR) thermal imaging is an emerging technology with promising industrial, scientific, space and medical applications. In general ROICs are made of using standard silicon technology to collect signals from the Infrared detectors arrays. Typical detector arrays are made on wafers of compound semiconductors, which are then bump bonded to silicon ROICs. ROIC circuit design of direct injection with correlated double sampling (CDS) has been proposed and implemented to meet the readout noise. The large charge handling has been achieved through optimum use of metal oxide semiconductor (MOS) capacitor. CDS removes the correlated noise by subtracting reset noise, offset from the signal. The performance of most of the infrared focal plan arrays (FPAs) are limited by large dark current.This then appears as an offset voltage in the ROIC output. This reduces the actual dynamic range of the ROIC. The offset resulting from dark current can be removed through a proposed skiming circuit which subtracts a preset current from the input current before integration. We have used a current mirror circuit for offset removal. An external off-chip trimming resistor has been provided for adjusting the trimming current. We have archived charge handling capacity of 11Me, readout noise of < 397 electrons and low power of < 128 mW with in pixel size of 30 µm×30 µm of 320×256 ROIC. |
