A High-Voltage DAC-Based Transmitter for Coded Signals in High Frequency Ultrasound Imaging Applications.

An ultrasound transmitter based on a high-voltage digital-to-analog converter (HVDAC) is presented in this paper. The transmitter is implemented in a 0.25- $\mu \text{m}$ high-voltage CMOS process provided by foundry, integrating the digital control circuitry and HVDAC on a single chip. By employing a fast-slewing DAC in conjunction with a standard DAC, the proposed circuit is optimized for high-...
