X-ray imaging is a widely used imaging modality in the medical diagnostic field due to its
availability, low cost, high spatial resolution, and fast image acquisition. X-ray photons in …

Modern X-ray imaging systems require low noise high-count-rate multichannel front-end
electronics. Such systems widely use charge-sensitive amplifiers (CSA) with pole-zero …

Abstract In K-Edge Subtraction (KES) imaging the K-edge of a high-Z contrast medium is
used to generate a differential image in which, in principle, only the contrast agent is visible …

We report on a novel technique of an in-pixel multilevel offset correction to be used in hybrid
pixel detector readout circuits operating in a single photon counting mode. This technique …

We report on the performance of a low noise and high count rate readout ASIC with binary
architecture and energy window selection for X-ray imaging applications using …

The paper describes the present status of the development of a portable, X-ray computer
tomography (CT) mini-system, whose detection part is based on a double array of 2× 1024 …

We present the design and simulation of the neural recording amplifier in the CMOS 180 nm
technology. Amplifier is capable of recording signals from mHz range up to kHz range while …

In this paper, the analysis of radiation detector noise is carried out based on digital signal
processing in the discrete time domain. To generate accurate noise models, detector noise …

Signal conditioning circuits, in particle energy spectrum determination systems, introduce
shaping characteristics that affect pulse integrity. This study explores algorithms to …

In this paper, we designed a beta ray sensor for a true random number generator. Instead of
biasing the gate of the PMOS feedback transistor to a DC voltage, the current flowing …
