Chen, C. (author), Chen, Z. (author), Chang, Z.Y. (author), Pertijs, M.A.P. (author)This paper presents a power- and area-efficient 9-channel LNA array for piezoelectric ultrasound transducers to enable real-time 3D imaging with miniature endoscopic and catheter-based probes. In view of the relatively low impedance of piezoelectric transducers, the LNA is implemented as a capacitive feedback voltage amplifier, rather than a...conference paper 2015
