Abstract

The basic operational principles and signal processing capabilities of the acoustic charge transport (ACT) device are presented. The ACT processor is a new type of high-speed GaAs charge transfer device in which electron transport is accomplished using the traveling wave electric field of a surface acoustic wave (SAW). The inherently smooth and continuous nature of traveling wave transport yields very high transfer efficiency, large signal bandwidths, and interference-free charge detection. Experimental results are presented for an ACT delay line operating at a 360-MHz SAW frequency with a transfer efficiency in excess of 0. 99994 and a signal bandwidth of 180 MHz. The nondestructive charge sensing (NDS) principles which form the basis for multiple-tapped delay line applications are discussed, and experimental results are presented for ACT transversal filters incorporating nondestructive-charge-sensing electrode arrays.
