ABSTRACT:
A delay device comprises a semi-conductor chip having acoustic charge transport channel disposed therein; a contact operably connected to and disposed at one end of the channel for injecting an electronic signal into the channel; a transducer for generating a single frequency, large amplitude acoustic surface wave through the channel for thereby transporting the electronic signal through the channel; a plurality of electrodes operably associated with the channel and disposed along the propagation path of the surface acoustic wave for non-destructively sensing the electronic signal; switches monolithically disposed on the chip and operably connected to the electrodes for preselecting any one of the electrodes, thereby extracting a delayed replica of the signal from the channel; and an output circuit for processing the extracted signal for generating an output.
