ABSTRACT:
A digital-to-analog converter for an acoustic charge transport (ACT) device that permits an ACT device to directly accept digital inputs. The digital-to-analog converter includes a plurality of digital-to-analog converter circuits that convert respective groups of digital information applied to the ACT device to corresponding analog voltages. The corresponding analog voltages are applied to respective input contacts that are isolated by charge barriers formed in a channel region of the ACT device. Each of the input contacts generates a charge packet having a charge magnitude corresponding to a numerical value of an input group of the applied digital information. The charge packets generated by each of the input contacts coalesces into a collective charge packet which then travels through the ACT device.
