Abstract:

Bioelectronic implants have enabled precise and closed-loop interfacing with biological systems to diagnose, monitor, and treat disorders. A critical challenge for these chronically implanted systems is the design of a robust, real-time wireless data uplink and a continuous, efficient wireless power delivery link within a severely constrained form factor. Ultrasound, …

Abstract:

This letter presents a compact and energy-efficient analog front-end (AFE) circuit for fully-digital beamforming in endoscopic and catheter-based 3D-ultrasound imaging. The AFE converts single-ended analog input from each transducer element into a 10-bit digital output through a low-noise amplifier (LNA) and a 20 MS/s SAR ADC. To minimize chip area …
