A Color Doppler Processing Engine with an Adaptive Clutter Filter for Portable Ultrasound Imaging Devices

ICASSP 2021accepted

This paper presents an optimized color Doppler processing engine for portable ultrasound devices. The imaging performance is improved by the proposed adaptive clutter filter that separates the clutter from the blood signal in the frequency-eigenvalue space. The adaptive clutter filter provides high…

ICASSP 2016accepted

This paper presents error-resilient sequential building blocks with time-borrowing capability without extra latches and generated clocks. The circuits are able to recover the timing errors caused by PVT variations and/or over-voltage scaling by up to half a cycle. Unlike prior works, the timing erro…
