Design And Implementation Of A Signal Conditioning Operational Amplifier For A Reflective Object Sensor, Ankit Master

Masters Theses

Industrial systems often require the acquisition of real-world analog signals for several applications. Various physical phenomena such as displacement, pressure, temperature, light intensity, etc. are measured by sensors, which is a type of transducer, and then converted into a corresponding electrical signal. The electrical signal obtained from the sensor, usually a few tens mV in magnitude, is subsequently conditioned by means of amplification, filtering, range matching, isolation etc., so that the signal can be rendered for further processing and data extraction.

This thesis presents the design and implementation of a general purpose op amp used to condition a reflective object …
