    摘要: A fast comparator circuit, including a plurality of first switches operating in parallel. A first data bit from a first data word is input into a first input of each first switch, and a corresponding second data bit from a second data word is respectively input into a second input of each first switch. Each first switch provides a first logic state output when the first data bit matches the corresponding second data bit or a second logic state output when the first data bit does not match the second data bit. A plurality of second switches receive the respective logic state outputs and produce a combined output, indicating an all match or a mismatch, to a third switch combination connected to a first branch node and a second branch node to create a first voltage difference between the first and second branch nodes when an all match output results and a second voltage difference between the first and second branch node when a mismatch output results. A sense amplifier operates to amplify the voltage differentials that develope due to an imbalance caused in the conductance at the two branch nodes.

    摘要: In a vidicon, optical energy enters through a transparent receiving surface (37) into a multilayer semiconductor monocrystalline body in which it is converted into hole-electron pair carriers in different particular overlying energy responsive layers (12, 13, 14) and the electrons thereof are collected in potential wells associated with the particular layer. Each pixel is isolated from adjoining pixels by isolation regions (20, 22), and readout contacts (26, 27, 29) for the layers are separated by isolation regions (28, 30).

    摘要: A virtual multi-port RAM (VMPRAM) structure has automatic port sequencing and single-port array density and speed. VMPRAM employs input-triggered, self-resetting macros in a pipelined architecture to provide multiple self-timed on-chip cycles during one machine cycle. The VMPRAM incorporates an SRAM segmented into many input triggered, self-resetting, fast cycling blocks. A timing signal is derived from a selected SRAM block for releasing the next select signals and data to the SRAM blocks. The SRAM block inputs are only the data input bus and the decoded signals needed to select a wordline and a bitline pair, and the SRAM block cycle is only the time needed to provide adequate pulse width for word lines and bitlines. Each SRAM block, and all the circuit blocks in the path to access the SRAM blocks, are input-triggered and self-resetting. The multiple address (35, 37, 39) and data input latches (55, 57, 59) are multiplexed at the driver to the true and complement buses to the SRAM segments, and those buses are self-resetting. Similarly, the selected SRAM block reads data out onto a self-resetting bus (63), and address (24, 26, 28) and data inputs (44, 46, 48) are latched in blocks that are set up for the release signal by the release of the adjacent block, and these blocks are all self-resetting.

    摘要: A digital shifter/rotator (1000) for shifting an input word by an amount depending on a shift control word (4000) is described. The shifter/rotator comprises an array of FET pass transistors arranged in a sequential number of stages (1200, 1400, 1600, 1700, 1800). The amount to be shifted in each stage is controlled by a corresponding shift control bit on lines 4200 of the shift control word buffered by drivers 4500, whereby the output word of the rotator is the input word shifted by an amount equal to a sum of the number of shifts effected in each of the stages as determined by the shift control word. The rotator features selectable amount of shift in one machine cycle, high performance and reduced device count. Further improved performance is obtained by utilizing decoupling devices for isolating the input points of the stages, except when providing rotation, from the long rotation cross buses and its associated large parasiticcapac- itances.
