ABSTRACT:
An acoustic charge transport device comprises a substrate with a layer disposed thereon; a channel disposed within the layer for providing a propagation path for a surface acoustic wave; a contact operably connected and disposed at one end of the channel for injecting an electronic signal into the channel; a transducer disposed at the one end of the channel for generating and propagating the surface acoustic wave through the channel; a plurality of sensing electrodes operably associated with the channel and disposed along the propagation path of the surface acoustic wave for non-destructively sensing the electronic signal; and a plurality of active buffer circuits each having an input operably connected to respective sensing electrode and an output operably connected to an output circuit.
