By deriving analytical formulae for the quantization accuracy of the acoustoelectric current, we reveal that: (1) the flatness of the current plateau for the typical present devices has reached the theoretical limit of about 100 ppm over a 1/1000 change of the gate voltage; (2) increasing the transp
