An analogue to digital converter (ADC) (1 ) is provided which comprises an signal sampling device (5), a signal comparison device (3), and a digital signal generator (7, 9, 11 ). An analogue signal to be converted to a digital signal is input into the ADC, the signal sampling device produces samples of the analogue signal, the signal comparison device receives the analogue signal and the analogue signal samples, performs a comparison between them and outputs comparison signals, and the digital signal generator receives the comparison signals and uses them to generate a digital signal. The signal sampling device may produce voltage samples or current samples of the analogue signal. |
