A Power-Optimized Cable Driver for Miniature Ultrasound Probes

This thesis discusses the architecture, circuit implementation and the simulation results of a cable driver for ultrasound imaging. This design is capable of providing higher bandwidth, better dynamic range, wider output swing, and ideal biasing voltage at the output terminal. <br/>The driver design starts from the analysis and simulation of the...

On-chip Switched-Capacitor DC-DC converter for CMUT Biasing

Capacitive micromachined ultrasonic transducer (CMUT) technology has been considered as a promising alternative for the conventional piezo electric-based technology in ultrasound imaging systems. Its potential advantages include better image quality, higher operational frequency, and ease of fabrication and<br/>integration with CMOS read-out...

A low-noise amplifier for ultrasound imaging with continuous time-gain compensation

This work presents a low-noise amplifier (LNA) for ultrasound imaging with built-in continuous time-gain compensation (TGC), which compensates for the time-dependent attenuation of the received echo signal and thus significantly reduces its dynamic range (DR). The proposed design combines the LNA and TGC functions in a single variable-gain...
