英文摘要	A novel CMOS snapshot readout structure called DCA (Direct-injection Charge Amplifier) for focal-plane array (FPA) is presented. The pixel circuit includes only four MOS transistors. Using PMOSFET as the reset transistor with careful layout design, this pixel circuit can not only keep the in-pixel-capacitance large enough, but also avoid the threshold voltage loss during the reset for the integration node. Thereby, charge capacity of the readout circuit is increased. Since the pixel circuit is very simple and this structure can eliminate the influence of column bus parasitic capacitance, it is very suitable for large-format small-pixel readout circuit. An experimental 128??128 DCA chip has been designed with 1.2-??m DPDM n-well CMOS technology. The charge handling capacity is 11.2pC with pixel size 50??50??m2. A description of the readout circuit structure, pixel circuit, detector model, operation principle and chip layout is given in detail. Both excellent simulation results and experimental results of the fabricated DCA readout chip are presented.; EI; 0; 11; 1454-1457; 29
