  • Frequency+Tunable+MEMS

    For more than three decades, Micro Electro Mechanical Systems (MEMS) have steadily transitioned out of research labs and into production forming a more than $10 billion market [1]. MEMS devices such as accelerometers, pressure sensors and microphones, to name a few, have seen immense utilization, particularly in the consumer electronics market, because of their compact sizes and minute power consumptions. In addition, these devices benefit from batch fabrication, which has enabled year-over-year reductions in cost [2]. In recent years,

  • High+Performance+RF+MEMS

    Micro-Electro-Mechanical Systems (MEMS) are miniature systems composed ofintegratedelectricalandmechanicalpartstosenseand/orcontrolthingsonaμmscale. The concept of MEMS is attributed to Richard Feynman’s famous talk on December 29th, 1959 [2,3]. Dr. Feynman foresaw many aspects of future MEMS development with his insight in microphysics. In particular, material properties in the μm scale are differentfrombulkpropertiesandthescalingdownofintegratedcircuits(IC)fabrication technology has been a major driving force of MEMS development.

  • 臺達PLC編程軟件技術手冊

    臺達的資料,給用的著的同學們。早期當各家 PLC 開發商紛紛建立自己的編程語言時,其各自不同的編程方式,對于用戶而言無疑是一個相當大的負擔;有鑒于此,由國際組織 I.E.C.(International Electro-technical Commission)所制定與推動的 IEC 61131-3 標準便由此應運而生。其主要的特色在于統整各家的編程特點,并考慮用戶的背景與習慣,而規范了一個可讓各家廠商與用戶共同依循的標準,并可讓符合 IEC61131-3 標準的程序代碼具備相當高的可讀性與兼容性。以下是關于 IEC 61131-3 的簡述。

  • AM2355n datasheet

    3-phase Sensor-less Fan Motor DriverAM2355NThe AM2355N is a 3-phase sensor-less DC fan motor driver IC. It senses the BEMF (BackElectro-Motive Force) of the motor in rotation and provides corresponding commutation current tothe motor. Rotation speed can be controlled by PWM input signal. The drivers include LockDetection, Thermal Shutdown, and Over-current Protection. Forward and Reverse control.www.junmintech.com
