Solid state devices combining the use of surface-acoustic-wave devices and charge-coupled devices |
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.
