Abstract
Based on the P-N-N-P type two-color infrared focal plane array( FPA) detector structure and its equivalent circuit, the principles and realization ways of a kind of 128×128 two-color infrared focal plane readout integrated circuit( ROIC) with successively integrating and simultaneously reading out have been proposed. The cell circuit using the direct injection (DI) structure as the input stage will acquire the larger integrating capacitors. This structure meets the demand that there are two independent signal channels for both the middle and short wavelength infrareds in a cell circuit. The simulation results show that the circuit meets the predetermined design requirements, the integrating time is adjustable, the readout rate is faster than or equal to 5 MHz, the linearity of the output voltages of MW and SW reach above 99%, the power dissipation is about 68 mW.
