摘要： A solid state device capable of providing long-term storage of analog signals which in a particular embodiment utilizes a plurality of MNOS storage elements. An input analog signal is applied to a plurality of temporary storage means each associated with an MNOS storage element for temporarily storing a charge proportional to the amplitude of the portion of the input analog signal applied thereto. Storage control means are used to transfer the temporarily stored charges to the long-term MNOS storage elements so that controlled amounts of carrier charges are stored in the nitride layers thereof, such controlled amounts being substantially linearly proportional to the temporarily stored charges associated therewith. In a particular embodiment the input analog signal may be supplied via a surface acoustic wave (SAW) device and coupled to the MNOS device directly or it may be coupled to a charge-coupled device (CCD) and thence coupled to the MNOS device.

摘要： A tapped delay line uses a varistor network for tap weighting. The varistors may be used in a resistive summing network or as amplifier gain control elements. In addition, the varistors can be programmed by a voltage programming circuit comprising a switch array, an input voltage programming bus, and sets of master and slave digital programming signals.

摘要： A solid state device combining the use of a surface-acoustic-wave (SAW) device and a charge-coupled device (CCD) which utilizes an interface means therebetween comprising a plurality of conductive fingers responsive to an acoustic wave on the SAW device. The conductive fingers are electrically connected at at least one end to the CCD substrate and a plurality of temporary storage means are used for temporarily storing a charge proportional to the voltage potential on the associated conductive finger. The temporary stored charges can be transferred to the storage wells of the CCD for storing a replica of the acoustic wave. The SAW-CCD combination is adapted for use as a buffer memory, an accumulating correlator, or as a matched filter device.
