Abstract
This chapter describes the theory and design of the different kinds of dynamic offset-cancellation techniques. These techniques can reduce the offset of an amplifier by a factor of 100 to 1000 and do not need trimming. Knowledge of these techniques is necessary to improve the accuracy of CMOS smart temperature sensors. Also in this chapter, a new technique is proposed that can even further reduce the offset. This technique is called the “nested chopper technique”. An implementation of this new technique is shown and measurement results are discussed.
