介绍了一种用于颈动脉三维超声成像的超声收发专用集成电路（ASIC）。这种应用需要数千个超声波换能器元件的阵列，远远超过传统成像系统的通道数量。<inline-formula> < text -math表示法="LaTeX">$3.6 times 6.8$ </ text -math></inline-formula> mm<sup>2</sup> ASIC接口一个<inline-formula> < text -math表示法="LaTeX">$24 times 40$ </ text -math></inline-formula>元件的PZT阵列，直接集成在ASIC的顶部，到一个仅使用24个发送和接收通道的成像系统。多个asic可以平铺在一起形成一个更大的阵列。该ASIC采用0.18 <inline-formula> < text -math符号="LaTeX">$mu ext{m}$ </ text -math></inline-formula>高压（HV） BCD工艺实现，由可重构开关矩阵和行级接收电路组成。每个元件都与一个紧凑的自启动高压发射开关，一个接收电路的隔离开关和可编程逻辑相关联，使各种成像模式成为可能。电学和声学实验成功地证明了ASIC的功能。此外，该集成电路已成功应用于三维成像实验。
This paper presents an ultrasound transceiver application-specific integrated circuit (ASIC) designed for 3-D ultrasonic imaging of the carotid artery. This application calls for an array of thousands of ultrasonic transducer elements, far exceeding the number of channels of conventional imaging systems. The <inline-formula> <tex-math notation="LaTeX">$3.6 imes 6.8$ </tex-math></inline-formula> mm<sup>2</sup> ASIC interfaces a piezo-electric transducer (PZT) array of <inline-formula> <tex-math notation="LaTeX">$24 imes 40$ </tex-math></inline-formula> elements, directly integrated on top of the ASIC, to an imaging system using only 24 transmit and receive channels. Multiple ASICs can be tiled together to form an even bigger array. The ASIC, implemented in a 0.18 <inline-formula> <tex-math notation="LaTeX">$mu ext{m}$ </tex-math></inline-formula> high-voltage (HV) BCD process, consists of a reconfigurable switch matrix and row-level receive circuits. Each element is associated with a compact bootstrapped HV transmit switch, an isolation switch for the receive circuits and programmable logic that enables a variety of imaging modes. Electrical and acoustic experiments successfully demonstrate the functionality of the ASIC. In addition, the ASIC has been successfully used in a 3-D imaging experiment.
