摘要： The invention provides apparatus and methods for detecting electromagnetic energy using an array of detectors arranged in at least one row and multiple columns. A single crystal body has multiple doped regions disposed therein. Each one of the detectors produces charge in a corresponding one of the doped regions in the body in response to electromagnetic energy impinging upon that detector. A first charge transfer device includes an output port and multiple serially coupled charge storage cells including multiple first charge transfer regions disposed in the body parallel to the row, or rows, of detectors. Multiple second charge transfer devices include multiple second charge transfer regions disposed in the body transverse to the row, or rows, of detectors and the charge storage cells. Each one of the second charge transfer regions is adapted to transfer charge produced in a corresponding one of the doped regions to a corresponding one of the charge storage cells. Each one of the doped regions corresponding to one of the detectors has a doping profile adapted to produce an electric field in a direction from the doped region toward a corresponding one of the multiple second charge transfer regions. Such an arrangement allows dual polarization detection with little or no modification of the system configuration.

摘要： An interface circuit for converting a differential input voltage, having a common-mode level within a first range, into a differential output voltage having a different, common-mode level. The circuit feeds current between a pair of variable current sources and a pair of input terminals adapted to receive the differential input voltage through a pair of resistors. The amount of current passing through the pair of resistors is related to the common-mode level of the input signal. The resistors produce the differential output voltage at the pair of output terminals with a common-mode level related to the common-mode level of the input voltage translated an amount related to the amount of current passing through them.

摘要： A high speed CMOS binary up/down counter having a 200 MHZ clock rate comprises a 4-bit counting section that may be concatenated in multiple 4-bit sections. The counter performs in an up-count mode or a down-count mode in accordance with the state of a mode select signal. Each stage of the 4-bit counting section comprises a propagate/kill/generate gate for determining the status of a carry signal to a next stage, except the last stage of a 4-bit section, which does not require such a gate because it is coupled to a carry-forward generator along with the outputs from the other preceeding stages in the section. Each 4-bit section performs the counting function through a successive process of modulo-two sums of a lower order carry and the current state of a counter stage without the need for cumbersome gating structures.

摘要： A variable field content addressable memory (VFCAM) unit cell comprises a 4-bit content addressable memory, a programmer and a field selector. A limited capability of comparing between limits is provided by using mask bits at the data line inputs to the VFCAM unit cell. A plurality of VFCAM unit cells may be cascaded vertically and horizontally to provide a Y words by X bits VFCAM array. The VFCAM array is programmable by a field code coupled to field partition logic which selects the same number of fields in all memory locations and the number of bits in each field, and an operational VFCAM system results when the VFCAM array is coupled to an input address decoder, an I/O register and an output encoder.
