Analogue-to-digital converter

摘要

An analogue-to-digital converter, ADC, for converting an analogue input signal (Vin) into a digital signal (output) is disclosed. The ADC comprises a correction unit (15) adapted to generate a correction signal, which offsets the output signal from a feedback DAC configured to produce an analogue representation of the digital signal (output) so that the offset output signal (Vdac) has the same common-mode or bias point as the input signal (Vin).
