Digital low drop-out regulator (D-LDO) with fast settling time and superior transient response is gaining increasing attention to make up for the deficiency of analog LDO. However, as traditional digital LDOs regulate output voltage code at a rate 1 bit per clock cycle, speed limited. In this paper, multi-bit conversion technique proposed improve speed. The achieved by an error detector adaptiv...

Host-specific toxins from Helminthosporium victoriae (HV) and Periconia circinata (PC) caused gradual decreases in the negative electropotentials of single cells of susceptible but not of resistant plants. When tissues were held in a standard nutrient solution, the decrease (depolarization) induced by HV toxin was approximately 50 mv/hr; the decrease induced by PC toxin was even more gradual. C...

The concept of complex fuzzy sets is a generalization of ordinary fuzzy sets. In this paper, we introduce the concept of complex fuzzy subhypergroups ($H_{v}$-subgroups) as well as the concept of complex anti-fuzzy subhypergroups ($H_{v}$-subgroups). We investigate their properties and their relations with the traditional fuzzy (anti-fuzzy) subhypergroups ($H_{v}$-subgroups), and we prove some ...

This paper presents the design and postlayout simulation results of a capacitor-less low dropout (LDO) regulator fully integrated in low-cost standard 180 nm Complementary Metal-Oxide-Semiconductor (CMOS) technology which regulates output voltage at 1.2 V from 3.3 to 1.3 battery over −40 120 °C temperature range. To meet with constraints system-on-chip (SoC) battery-operated devices, ultralow p...

A 180-GHz signal source based on a 65-nm CMOS technology has been developed in this study. The 180-GHz signal source consists of a 90-GHz fundamental-mode Colpitts oscillator and a 180-GHz frequency doubler. A coupled-line is employed to couple two oscillator cores for generating a differential signal, which is delivered to the input of the differential-mode doubler. The fabricated signal sourc...

AIM The aim of the present study was to assess the change in physical properties (surface roughness, surface hardness and phase transformation) after surface grinding of zirconia by using three commercially available abrasives. MATERIALS AND METHODS Thirty sintered zirconia specimens were prepared and divided into three groups namely Group M (grinded using Mani Dia diamond bur standard grit),...

1 The discovery of the supersoft X-ray source RX J0527.8–6954 during the ROSAT first light observation (Trümper et al. 1991) of the Large Magellanic Cloud (LMC) in June 1990 has directed some attention to the optical variable HV 2554 because its location is within the X-ray error circle of RX J0527.8–6954 (Trümper et al. 1991, Greiner et al. 1991). Later ROSAT observations improved the X-ray po...
