WebAbstract 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. WebThe Allegro chopper stabilization technique, Dynamic Quadrature Offset Cancellation (U.S. Patent No. 5621319, 1997, now expired), removes key sources of the output drift induced by thermal and mechanical stresses. This offset reduction technique is based on a signal modulation-demodulation process.
