“…In this section, a high performance, 640×512 pixels, readout integrated circuit (ROIC) with snapshot mode integration is proposed and described. Typically, the ROIC consists of charge integration, charge to voltage conversion, pixel voltage multiplexing, signal transfer and amplification stage [16][17][18]. In our work, the block diagram of the readout structure consists of the block diagram of the readout structure plotted in Fig.…”

“…This error distorts the input signal of the ROIC and generates an unreliable final output signal. Various reports have been published on this problem over a long period of time [1][2][3][4]. Now, we have proposed a differential input mode ROIC instead of the conventional single input mode ROIC to decrease the errors that described above.…”

In this paper, high performance read-out integrated circuits (ROIC) for infrared (IR) image sensor applications is proposed. Because an uncooled microbolometer image sensor, used in an IR image sensor, is made by a micro electro mechanical systems process, the resistance of bolometer by each process does not appear same value under same temperature condition. This resistance variation generates a different output signal for same input by each chip. In order to improve on these drawbacks, a ROIC, which compensates for the error described above, was designed. Instead of a single input mode, a differential input mode ROIC was proposed and thus, a new circuit structure was proposed. Using results from a computer simulation, improvements such as that the effect of the process error was decreased 10-12% without an additional compensation circuit was found. Based on the simulation results, a prototype device including a ROIC and a micro bolometer with 16 9 16 cell arrays was fabricated and characterized.
