A novel approach to the dynamic supply current sensing based on the measurement of voltage drop across a parasitic resistance of the supply voltage metal line is presented. Then, auto-zero technique for voltage comparator offset cancellation, which provides very accurate and sensitive low voltage measurement is proposed. Therefore, we may use this as a current monitor for dynamic current testin...

Continued research into the development of III–V high-electron mobility transistors (HEMTs), specifically the minimization of the device gate length, has yielded the fastest performance reported for any three terminal devices to date. In addition, more recent research has begun to focus on reducing the parasitic device elements such as access resistance and gate fringing capacitance, which beco...

Larval trematodes frequently castrate their snail intermediate hosts. When castrated, the snails do not contribute offspring to the population, yet they persist and compete with the uninfected individuals for the available food resources. Parasitic castration should reduce the population growth rate lambda, but the magnitude of this decrease is unknown. The present study attempted to quantify t...

Abstract: We developed a low parasitic light sensitivity (PLS) and low dark current 2.8 μm global shutter pixel. We propose a new inner lens design concept to realize both low PLS and high quantum efficiency (QE). 1/PLS is 7700 and QE is 62% at a wavelength of 530 nm. We also propose a new storage-gate based memory node for low dark current. P-type implants and negative gate biasing are introdu...

In this paper, a systematic design method producing balanced current-mode filters is proposed, using current controlled fully balanced second-generation current conveyor circuit (CFBCCII). In this method, many kind of all-pole multiple loop feedback (MF) current mode balanced filters can be obtained, all the produced filters have fully balance structures. Moreover, the frequency of the filters ...

neurocysticercosis, is the infection caused by the larval form of the tapeworm taenia solium. it is considered as the most common parasitic disease of the central nervous system and the most common cause of acquired epilepsy. this has primarily been a disease that remains endemic in countries with poor economy , but because of increased migration neurocysticercosis is being diagnosed more frequ...

Parasitic protozoa infecting humans have a staggering impact on public health, especially in the developing world. Furthermore, several protozoan species are major pathogens of domestic animals and have a considerable impact on food production. In many instances, the parasites have developed resistance against available chemotherapeutic agents, making the search for alternative drugs a priority...

parasitic colitis, especially entamoeba histolytica, is a well-known disorder in the middle east particularly in iran. the carrier state of the disease or the chronic type frequently remains undiagnosed or mistaken as irritable bowel syndrome which results in further discomfort and increases the incidence of associated complain. we devised a technique by inserting bisacodyl suppository and then...

as a part of a major ecological study of hanna wetland, semirum region, isfahan province, parasitic infestation of 3 native and one introduced fish species were investigated. a total of 120 fish specimens were collected by both cast net and a series of gillnets between fall and winter 2007, and spring and summer 2008. some of the observed parasites are reported for the first time as new host re...

results bulinus truncatus was detected in seven locations. in addition, melanoides tuberculata, which is also considered medically important, and physa acuta were detected. the prevalence of bulinus truncatus, melanoides tuberculata, and physa acuta was 6%, 5.5%, and 88.5%, respectively. background bulinus truncatus is the intermediate host of schistosoma haematobium, which is a causative agent...
