Abstract :
This paper introduces analytic and numerical methods to optimise the dynamic range of a third-order sigma-delta analogue-to-digital converter (ADC). Quantisation noise in a specified bandwidth is predicted and expressed relative to the maximum sinusoidal output from the ADC, for a range of design parameters, in order to establish the optimum design to achieve maximum dynamic range.
