Department of Electrical Engineering‚ Indian Institute of Technology‚ Madras 600 036‚ India Received 19 March 1995; revised 10 May 1996 Abstract A microcontroller based scheme for LCR measurement is described. The unknown element (an inductor or a capacitor or a resistor) is measured employing a non conventional ac bridge. The element to be measured forms one arm (side) of the bridge and the second (series) arm is made up of a simple resistor. A Multiplier type Digital to Analog Converter (MDAC)‚ controlled

THE BIOCHIPS Biochips: The most exciting future technology is an outcome of the fields of Computer science‚ Electronics & Biology. Its a new type of bio-security device to accurately track information regarding what a person is doing‚ and who is to accurately track information regarding what he is doing‚ and who is actually doing it. It’s no more required with biochips the good old idea of remembering pesky PINs‚ Passwords‚ & Social security numbers. Introduction: Biochips are any

The design and modeling of microscale electro-mechanical systems (MEMS) is a unique engineering discipline. At small length scales‚ the design of resonators‚ gyroscopes‚ accelerometers‚ and actuators must consider the effects of several physical phenomena. MEMS devices and sensors may even utilize multiphysics phenomena for its very function or for increased sensitivity. To this end‚ the MEMS Module provides user interfaces for electromagnetic-structure‚ thermal-structure‚ or fluid-structure interactions

Member‚ IEEE‚ and Zhengming Zhao‚ Senior Member‚ IEEE Abstract—A novel soft-switching boost converter with a magnetically coupled resonant snubber is presented in this paper. The passive snubber circuit‚ which is composed of two diodes‚ two capacitors‚ and one coupled inductor‚ ensures a zero current turn-on and zero voltage turn-off conditions for the power switch‚ and alleviates the reverse-recovery problem for the output diode. Moreover‚ with the proper design of the snubber circuit‚ the

at temperatures below 150 C. Tantalum is virtually resistant to corrosion due to an oxide film on its surface. Applications Tantalum finds use in four areas: high-temperature applications‚ such as aircraft engines; electrical devices‚ such as capacitors; sirurgical impants and handling corrosive chemicals. It is rarely used as an alloying agent because it tends to make metals brittle. Tantalum resist corrosion and is almost impervious to chemical attack‚ for this reason it has been employed in
