✦ Synopsis

This book shows the steps from data sheets of sensors to the extraction of model parameters for the program PSPICE in order to realize circuit analyses. Physical ENTITIES as temperature, humidity, light, pressure and sound are included by equations. The simulation concerns temperature displays, characteristics of humidity-sensors, light-to-voltage Converters, strain gauges, reed relays and Piezol-electric-sounders US-Converters and SAW Components
