Imperfections in analog-to-digital conversion (ADC) cannot be ignored when signal digitization requirements demand both wide dynamic range and high resolution, as is the case for Majorana Demonstrator 76Ge neutrinoless double beta decay search. Enabling experiment's high-resolution spectral analysis efficient pulse shape discrimination required careful measurement correction of ADC nonlinearite...

background diffusion-weighted imaging (dwi) is a form of magnetic resonance imaging (mri) based on measuring the random brownian motion of water molecules within the biological tissues and is particularly useful in tumor characterization. objectives the purpose of this study was to evaluate the diagnostic value of dw mri and the apparent diffusion coefficient (adc) for preoperative grading of a...

Evaluation of vascular disrupting treatment (VDT) is generally based on tumor size and enhancement on conventional magnetic resonance imaging (MRI) which, unfortunately, may be limited in providing satisfactory information. The purpose of the study is to evaluate consecutive changes of 20 rabbit VX2 liver tumors after VDT by dynamic contrast-enhanced MRI (DCE-MRI) and diffusion-weighted imaging...

This paper presents a di erential input ash ADC with digital common mode rejection (DCMR) and dithered, noise shaped requantization used in a high-performance, single-poly CMOS ADC modulator IC. By avoiding the use of metal-metal capacitors, the DCMR ash ADC required 14% less area than a switched-capacitor implementation and avoided circuit implementation problems. Measurements and analysis sho...

This study was designed to calculate the critical velocity (vcrit) and anaerobic distance capacity (ADC) of prepubescent children for running events. Thirty-four prepubertal children underwent a graded field test to exhaustion in order to determine peak oxygen uptake (peak VO2) and maximal aerobic velocity (MAV). Then, in random order, they performed five runs to exhaustion (tlim) at relative v...

This paper presents MOSFET based analog to digital converter which is simple in design, has high resolution, and conversion rate better than dual slope ADC. It has no DAC which will limit the performance, no error in conversion, can operate for wide range of inputs and never become unstable. One of the industrial applications, where the proposed high resolution MOSFET ADC can be used is, for th...

OBJECTIVE To determine whether a change in apparent diffusion coefficient (ADC) value could predict early response to CT-guided Oxygen-Ozone (O2-O3) injection therapy in patients with unilateral mono-radiculopathy due to lumbar disc herniation. MATERIALS AND METHODS A total of 52 patients with unilateral mono-radiculopathy received a single intradiscal (3 mL) and periganglionic (5 mL) injecti...

This work presents a hybrid column-parallel TDC-interpolated Single-Slope ADC which uses a digital feedback to solve the delay element and clock period matching problem in Flash TDC-Interpolation of SS ADCs. The presented feedback correction scheme is applied in-column and occurs online after the end of each conversion, occupying less than 5% of the ramp time at 12-bits. The concept of the arch...

This paper proposes a distributed ramp signal generator of column-parallel single-slope ADCs for CMOS image sensors. This architecture does not require any power-hungry amplifiers of the conventional one but consists of miniaturized column-wise ramp signal generators connected together by metal wires, which achieves high linearity and high uniformity. Simulation results show less than 1LSB nonl...
