Design, Modeling and Simulation of Microhotplate in Gas Detection Application

In this paper, the modeling and design of the platinum Microhotplate (MHP) for gas sensing applications using Coventorware is presented. The MHP is designed to achieve good temperature uniformity with low power dissipation. The length of MHP microbridges are varied from 120 to 200 while the width of...
