Chen, C. (author), Pertijs, M.A.P. (author)As medical ultrasound imaging moves from conventional cart-based scanners to new form factors such as imaging catheters, hand-held point-of-care scanners and ultrasound patches, there is an increasing need for integrated transceivers that can be closely integrated with the transducer to provide channel-count reduction, improved signal quality...journal article 2021

Guo, P. (author), Chang, Z.Y. (author), Noothout, E.C. (author), Vos, H.J. (author), Bosch, Johan G. (author), de Jong, N. (author), Verweij, M.D. (author), Pertijs, M.A.P. (author)This article presents a compact analog front-end (AFE) circuit for ultrasound receivers with linear-in-dB continuous gain control for time-gain compensation (TGC). The AFE consists of two variable-gain stages, both of which employ a novel complementary current-steering network (CCSN) as the interpolator to realize continuously variable gain....journal article 2022

Kang, E. (author), Tan, M. (author), An, J. (author), Chang, Z.Y. (author), Vince, Philippe (author), Sénégond, Nicolas (author), Mateo, Tony (author), Meynier, Cyril (author), Pertijs, M.A.P. (author)This article presents a low-noise transimpedance amplifier (TIA) designed for miniature ultrasound probes. It provides continuously variable gain to compensate for the time-dependent attenuation of the received echo signal. This time-gain compensation (TGC) compresses the echo-signal dynamic range (DR) while avoiding imaging artifacts...journal article 2020
