| Title | High-Speed High-Voltage Ultrasound Driver Design |
| Summary | Ultrasound is an emerging imaging modality widely used in distance ranging and biomedical imaging applications. A pulser circuit is required to drive the ultrasound transducer to generate acoustic wave. Due to the characteristic of ultrasound transducer, transmitter output voltage is usually above 10V and the receiver input voltage is in millivolt range. Hence the transmitter circuit needs to withstand high voltage. Special high voltage process such as Bipolar-CMOS-DMOS (BCD) process is required for the design of high voltage circuit. Voltage level conversion is required to convert the signal from low voltage domain to high voltage domain to drive the transmitter. In this project, students will explore the design of high-voltage driver in transmitter. The proposed research consists of the following two major tasks covering from basic design methodology to transistor level circuit implementation. (1) System level analysis to explore new transmitter circuit structure with wide dynamic range, high energy efficiency and high linearity. (2) Circuit parameters optimization for different frequency bands and loading conditions. The circuit design will be performed in Cadence EDA tool in advanced process node GF 55nm BCDLite. |
