More Facts about Sensing Elements

Abstract

This chapter is meant to add a few details which were deliberately left out in the earlier chapters as such facts might have caused a distraction from the application being described. Even so it is not intended to explain the operation of semiconductors, such as transistors, using Solid State Physics but only to consider them in their simplest form as current controlled switches and amplifiers. For a more rigorous description, some references to other suitable books are provided in Further Reading (page 143) at the end of the book. The information given is therefore only intended to assist the reader to understand how the sensors and circuits describe previously operate and is not meant to be a comprehensive guide to all electronic sensors.
