Abstract
An analogue-to-digital (A/D) converter converts an analogue input signal to a digital code representing the analogue input signal. The A/D converter includes a comparator for comparing the input signal with a reference signal, a search logic block for determining the digital code, and an A/D converter arranged for receiving input from the search logic block and for providing the reference signal to be applied to the comparator. At least a first portion of the A/D converter is implemented with equal capacitors and may be controlled by a thermometer coded signal. Additionally, the A/D converter may include a second portion implemented using binary weighted capacitors controlled by a thermometer coded or binary coded signal. The A/D converter may also include a plurality of A/D converters coupled by an analogue addition circuit or a weighted summing amplifier.
