(author), Verweij, M.D. (author), de Jong, N. (author), Pertijs, M.A.P. (author)This article presents an application-specific integrated circuit (ASIC) for catheter-based 3-D ultrasound imaging probes. The pitch-matched design implements a comprehensive architecture with high-voltage (HV) transmitters, analog front ends, hybrid beamforming analog-To-digital converters (ADCs), and data transmission to the imaging system....journal article 2024

(author), Verweij, M.D. (author), de Jong, N. (author), Pertijs, M.A.P. (author)In this letter, a compact high-voltage (HV) transmit circuit for dense 2-D transducer arrays used in 3-D ultrasonic imaging systems is presented. Stringent area requirements are addressed by a unipolar pulser with embedded transmit/receive switch. Combined with a capacitive HV level shifter, it forms the ultrasonic HV...journal article 2022

Kim, Taehoon (author), Fool, F. (author), Simoes dos Santos, D. (author), Chang, Z.Y. (author), Noothout, E.C. (author), Vos, H.J. (author), Bosch, Johan G. (author), Verweij, M.D. (author), de Jong, N. (author), Pertijs, M.A.P. (author)This paper presents an ultrasound transceiver application-specific integrated circuit (ASIC) directly integrated with an array of 12 × 80 piezoelectric transducer elements to enable next-generation ultrasound probes for 3D carotid artery imaging. The ASIC, implemented in a 0.18 µm high-voltage Bipolar-CMOS-DMOS (HV BCD) process, adopted a...journal article 2021

(author), Verweij, M.D. (author), de Jong, N. (author), Pertijs, M.A.P. (author)This paper presents an area- and power-efficient application-specified integrated circuit (ASIC) for 3-D forward-looking intravascular ultrasound imaging. The ASIC is intended to be mounted at the tip of a catheter, and has a circular active area with a diameter of 1.5 mm on the top of which a 2-D array of piezoelectric transducer elements is...journal article 2018

(author), Verweij, M.D. (author), de Jong, N. (author), Pertijs, M.A.P. (author)This paper presents an ultrasound transceiver application-specific integrated circuit (ASIC) designed for 3-D ultrasonic imaging of the carotid artery. This application calls for an array of thousands of ultrasonic transducer elements, far exceeding the number of channels of conventional imaging systems. The 3.6 x 6.8 mm² ASIC...journal article 2018
