Sampling time effects in the ACT device.
The signal-dependent sampling process in an acoustic charge transport (ACT) device is demonstrated. Theoretical calculations and experimental measurements show the direct effect of gate voltage, wave amplitude, and transport depth on the sampling interval. A decrease in gate voltage and transport depth, and an increase in wave amplitude, are shown to reduce the increase in sampling time delay for a fixed transport current. An analysis of the distortion generated by this nonuniform sampling is performed, and a channel-current-intercept value is computed for a typical ACT device.
