英文摘要	An improved low power CMOS snapshot readout structure called OESCA (Odd-Even Snapshot Charge Amplifier) for focal plane array (FPA) is presented in this paper. Using two low power charge amplifiers as column readout circuit (one is for the odd-row readout and the other is for the even-row), this structure not only can eliminate the influence of column bus parasitic capacitance, but also can save 15% power dissipation of the column readout stage. The pixel circuit includes only three NMOSFETs. Thus, it is very suitable for large-format small-pixel lower-power readout circuit. An experimental 64 X 64 OESCA chip has been fabricated with 1.2-mum Double-Poly Double-Metal (DPDM) n-well CMOS technology. The charge handling capacity is 10.37pC with pixel size 50 X 50mum(2). A description of the readout circuit structure, pixel circuit, operation principle is given in detail. Both excellent simulation results and experimental results of the fabricated OESCA readout chip are presented.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000176369900203&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Computer Science, Information Systems; Engineering, Electrical & Electronic; Telecommunications; CPCI-S(ISTP); 2
