【Abstract】 Acoustic Charge Transport (ACT) technology which appeared at the beginning of 1980’ s is a new type of signal processing technology with high frequency and high velocity, and is the main developing trend in analogue signal processing field. In this paper, the design and fabrication of ACT delay line are reported. Some key techniques are discussed. Excellent performance of the experimental device has been achieved: Tdelay≈ 1 Ps operating at the surface acoustic wave (SAW) clock frequency of 358 MHz.更多还原
