摘要： A transversal filter of the split electrode type employing a bucket-brigade device (BBD) is described. The BBD wells extend beyond the edges of the clocked gates of the BBD below second gates of different areas. These mask programmed second gates provide the filter output. Unlike other split electrode, capacitance sensing filters, these gates are not clocked, thus the filter has simplified output circuitry and a greater dynamic range.

摘要： The present invention is to make a switch out of two diodes to read out a third photosensitive transducer which integrates and stores the photon-generated carriers. The switching diodes are arranged so that during their on time, the switching resistance remains linear and constant throughout the photosensitive transducer readout time independent of the number of photon-generated carriers that are stored in the photosensitive transducer. To maintain a low constant on resistance, the two switching diodes in series are pulsed simultaneously with complementary pulses applied to the two terminals of the series diodes to forward bias them during the readout period. The third is a photosensitive transducer, which is connected to the series node of the switching diodes such that the photosensitive diode is always in a reversed bias condition, whether it is in a readout or integration mode. The remaining terminal of the diode is connected to an output circuit which detects the photon-generated carriers when the switching diodes are pulsed in a forward biased condition during the readout period. Then, during the integration mode, the pulse is removed, the switching diodes are reverse biased, and the photosensitive transducer accumulates the photon-generated carriers.

摘要： A semiconductor filtering apparatus substantially fabricated as a metal-oxide-semiconductor (MOS) integrated circuit that permits discrete time correlation or convolution of an analog input signal with a binary or analog correlating signal. The apparatus may also be employed as a recursive filter. A plurality of novel bucket-brigade charge transfer means are employed to shift the input analog signal past non-destructive read-out taps. Electrically programmable floating gate devices are used to store either a binary or analog correlating signal. The sum or difference signal associated with each of the plurality of charge transfer means is weighted to produce the final filter output in one embodiment.
