How Double-Sampling Integrators Supercharge Sigma-Delta Modulators!
What Double-Sampling Integrators Are All About Double-sampling integrators are powerful signal-processing techniques widely used in electronics, sensors, and measurement systems. Their core idea is simple but effective: instead of sampling a signal once, the system samples it twice in a controlled sequence and integrates the difference. This approach helps cancel out unwanted noise, offsets, and drift that often degrade measurement accuracy. As a result, double-sampling integrators deliver cleaner and more reliable signals. Why Single Sampling Falls Short In real-world systems, measurements are rarely perfect. Thermal noise, low-frequency drift, and offset errors can significantly distort signals—especially in low-level or precision applications. Single-sampling methods capture both the true signal and these unwanted artifacts together. Double-sampling integrators overcome this limitation by separating signal information from systematic errors, making them especially valuable ...
