Abstract
Bucket Brigade Device (BBD) adding-delay architecture was proposed as the analog beamformer for piezoelectric micromachined ultrasonic sensor phased array. BBD adding-delay architecture were used both as delay and adding elements, and the input signals were distributed adding in the process of delay. This architecture was useful to reduce chip area, simplify system design, and realize on-chip integration. Combining piezoelectric micromachined ultrasonic array sensors and the analog delay-sum circuits successfully performed two-dimensional object detection.
