An ASIC design of a programmable gain instrumentation amplifier for a universal signal conditioner

By: Call Number: AIT Thesis no.ME-01-02 Contributor(s): Material type: SeriesSeries: Asian Institute of Technology. Thesis ; no. ME-01-02Publication details: Bangkok : Asian Institute of Technology, 2001Description: 106 pSubject(s): Online resources: Dissertation note: Thesis (M.Eng.) - Asian Institute of Technology, 2001 Summary: Many sensors and transducers used for real world applications demand the need for a signal conditioning system. The complete universal signal conditioning system is very complex and includes multiple functions, such as multiplexing, signal amplification, attenuation, filtering, electrical isolation, simultaneous sampling and digital to analog conversion. This thesis describes the development of a Programmable Gain Instrumentation Amplifier (PGIA) to be used for the universal signal conditioner. The demand for low-level signal conditioning at high CMRR puts up the challenge of developing a precise and efficient instrumentation amplifier. The gain setting can be either software based or hardware, allowing the user more flexibility in using the PGIA for desired applications.

Many sensors and transducers used for real world applications demand the need for a signal conditioning system. The complete universal signal conditioning system is very complex and includes multiple functions, such as multiplexing, signal amplification, attenuation, filtering, electrical isolation, simultaneous sampling and digital to analog conversion. This thesis describes the development of a Programmable Gain Instrumentation Amplifier (PGIA) to be used for the universal signal conditioner. The demand for low-level signal conditioning at high CMRR puts up the challenge of developing a precise and efficient instrumentation amplifier. The gain setting can be either software based or hardware, allowing the user more flexibility in using the PGIA for desired applications.
