inter organizational collaboration has been considered as a novel concepts in supply chain management by many researchers. in this paper two groups of internal and external factors were examined in relationship with inter-organizational collaboration in iran khodro supply chain. internal factors consist of organizational strategy and technology and inter-organizational factors refers to trust a...
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
In this paper a novel very high performance current mirror is presented. It favorably benefits from such excellent parameters as: Ultra high output resistance (36.9GΩ), extremely low input resistance (0.0058Ω), low output (~0.18V) and low input voltage (~0.18V) operation, very low power consumption (20μW), very low offset current (1pA), ultra wide current dynamic range (150dB), and ultra high a...
Blind and low vision students as a group of special needs students can use computer. The progress of technology with the combination of Braille and conversion of text to speech caused to make technological equipments and input / output devices of computer for Blind and low vision students. In this issue, we introduce these devices and their recent models in order to design them.
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
In this work we present a high-speed optical receiver with external large-area photodiode. The optical receiver is realized in 0.35μm SiGe BiCMOS technology. The input circuit is a two-transistor transimpedance amplifier using an common-emitter and an emitter-follower configuration. An external silicon PIN photodiode of a squared area of 0.25mm2 with a rise time of 0.4ns at 850nm light is used....
