2009_Book_Dynamic Offset Compensated CMOS Amplifiers.pdf

CMOS amplifiers suffer from relatively poor offset specifications. Since the 1980s techniques have been explored to calibrate for this offset, or to let the amplifier itself compensate for its offset in some way or another. This latter approach is often done dynamically during operation of the amplifier, hence the name “dynamic offset compensation”. This thesis describes the theory, design and realization of dynamic offset compensated CMOS amplifiers. It focuses on the design of general-purpose broadband operational amplifiers and instrumentation amplifiers.
