A 6-bit, 7 mW, 700 MS/s subranging ADC using Capacitive DAC (CDAC) and gate-weighted interpolation fabricated in 90 nm CMOS technology is demonstrated. CDACs are used as a reference selection circuit instead of resistive DACs (RDAC) for reducing settling time and power dissipation. A gate-weighted interpolation scheme is also incorporated to the comparators, to reduce the circuit components, po...

Abstrac tIn the paper, the enhanced version of time-to-digital converter with self-timed successive charge redistribution is presented. In the proposed solution, time-to-charge mapping realized by constant rate charge accumulation is run concurrently to the charge redistribution in the binary-weighted capacitor array. By introducing concurrent charge accumulation and redistribution, the convers...

BACKGROUND Junctophilin-2 (JPH2) is the primary structural protein for the coupling of transverse (T)-tubule associated cardiac L-type Ca channels and type-2 ryanodine receptors on the sarcoplasmic reticulum within junctional membrane complexes (JMCs) in cardiomyocytes. Effective signaling between these channels ensures adequate Ca-induced Ca release required for normal cardiac contractility. D...

This work analyzes the advantages of broad-band time-domain the electrical measurement applied to electromagnetic interference (EMI) problems. The digital signal processing of EMI measurements allows to emulate in real-time the various modes of conventional analogous equipment. Since time-domain techniques allow processing the amplitude and phasing information of the whole signal spectrum in pa...

This paper presents a detailed small-signal and transient analysis of a full bridge PWM DC-DC converter designed for high voltage, high power applications using an average model. The derived model is implemented in a typical system and used to produce the small-signal and transient characteristics of the converter. Results obtained in the analysis of the high voltage and high power design examp...

We propose a neutron diffractometer system based on MgB2 thin film detectors and an SFQ signal processor. Small dimensions of MgB2 thin film detectors and high processing capability of the single flux quantum (SFQ) circuits enable us to handle several thousand or more detectors in a cryocooler, leading to a very compact system. In addition, the system can provide many diffraction patterns for d...

BACKGROUND/AIM Reduced systemic antioxidant defence is considerd to play an important mediating role in pathogenesis of diabetic neuropathy. The aim of this study was to evaluate if the total antioxidant blood capacity (TAC) is reduced in patients with type 2 diabetes mellitus (DM) and diabetic distal symmetrical polyneuropathy (DDSP) and to correlate this antioxidant capacity with the degree o...

This paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. The power filter integrates a passive power filter which is a RL low-pass filter placed in series with the load, and an active power filter which comprises an RL in series with an IGBT based voltage source converter. The filter is assumed...

As one of the most widely used acidic condiments in world, vinegars have demonstrated physiological functions. Due to their polyphenol content, blueberries (Vaccinium myrtillus L.) are a valuable source natural flavours and antioxidants for vinegar production. Ultrasound treatment is recognized as an effective technique improving extraction yield bioactive compounds from various plant materials...
