    摘要： A successive approximation register, SAR, analog-to-digital converter, ADC, (400) is described. The SAR ADC (400) includes: a track and hold circuit (414) configured to sample an analog input signal (410); a comparator (416) coupled to the track and hold circuit and configured to compare the sampled analog input signal (410) with a DAC (444) output voltage; and a feedback path (422) that comprises a digital-to-analog converter, DAC, (444) configured to generate the reference voltage that approximates the input analog signal (410). The SAR ADC (400) further includes a dither circuit (468) coupled to or located in the feedback path (422) and arranged to add a dither signal at an input of the DAC (444) in a first time period and subtract the dither signal from the output digital signal routed via the feedback path (422) and input of the DAC (444) in a second time period during a conversion phase of the SAR ADC (400).

    摘要： Various exemplary embodiments relate to a tracking system and method. The system includes a transistor switch having a gate node and a source node, a power source circuit connected to the gate node, and a bootstrapping circuit connected to the source node and to the gate node. The power source circuit charges the switch during a first tracking phase, and the bootstrapping circuit charges the switch during a second tracking phase.

    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).
