This paper investigates the application of Active Noise Cancellation (ANC) techniques in improving the performance of sigma delta ADCs. Using a specific technique of ANC, adaptive line enhancer (ALE), quantization noise of sigma delta modulator can be reduced significantly and signal to noise ratio is boosted. Mathematical model of this system in steady state is presented. Simulation results on different sigma delta ADCs are very promising and show significant improvements in signal to noise… CONTINUE READING
