WebAlthough fully split ADC structure remedies the interference issue, there can be an increase in analogue complexity [4]. In this Letter, a dither-based calibration technique with fast conver-gence speed is proposed to correct bit-weight errors in pipelined-SAR ADCs. The input signal interference is mostly eliminated by splitting only the second ...

WebFor applications where the performances of the high-speed ADC in the frequency domain is the main critical parameter for the system overall performances, it is possible to improve the ADC response thanks to dither. Dithering can be defined as adding some white noise, which has the effect of spreading low-level spectral components.

WebNov 2, 2014 · The act of dithering helps this process by decorrelating the quantization noise. Consider a simple example where a constant (not sinusoidal) signal is sent into a 1bit ADC. If the signal is at 0.75 (ignore units) and the ADC can, depending on its input, either output a 0.0 or 1.0, the signal will be reported as a 1.0 till the cows come him.
