This article presents a fully integrated 64-channel programmable ultrasound transmit
beamformer for catheter-based ultrasound probes, designed to interface with a capacitive …

An 8-channel ultrasound receiver compatible with in-probe electronics for 3-D ultrasound
imaging is proposed. It has eight analog front-ends for signal conditioning and a …

Analogue-to-digital converters (ADC) using oversampling technology and the Σ-∆
modulation mechanism are widely applied in digital audio systems. This paper presents an …

Ultrasonic imaging has become a very promising technology, and it has been widely applied
in biomedicine, geology, and other fields due to its advantages of safety, nondamaging, and …

Flexible and wearable devices are of great demand with the developing of the sensors and
IoT (internet of the things). The power consumption and volume of the devices need to be …

The problem of 3D objects orientation recognition in a three-dimensional image space is
considered in this paper. The used method is a quaternion-based approach applied to …

D ultrasound imaging using a 2-D array provides much more information about our body
than conventional 2-D imaging. However, due to the large number of elements in a 2-D …

This work presents a low-noise amplifier (LNA) for ultrasound imaging with built-in
continuous time-gain compensation (TGC), which compensates for the time-dependent …

This thesis discusses the architecture, circuit implementation and the simulation results of a
cable driver for ultrasound imaging. This design is capable of providing higher bandwidth …

Zero-Crossing-Based Integrators (ZCBIs) are energy-efficient alternatives to conventional
switched-capacitor integrators that are typically implemented using operational …
