Abstract :
We describe a new oversampled encoding scheme that explicitly minimizes quantization error through the use of a nonlinear controller. The approach is theoretically stable, suitable for mixed-signal integrated circuit implementation and effectively suppresses spurious tones. Theory and simulation results are presented.
