"WebFor an ADC, SFDR is defined as the ratio between the rms amplitude of the single tone and the rms amplitude of the worst spur. Because the SFDR requirements for narrowband air standards are so demanding, it is desirable to achieve the best possible SFDR from the ADC. One technique that is used to improve SFDR is dither.

WebFeb 27, 2024 · The other thing to keep in mind is that one full cycle of the 480Hz PWM takes ~2 milliseconds, but 256 readings at a 500kHz ADC clock takes only 6.73 milliseconds – so there is a high probability that dither signal synchrony issues creep in at the higher ADC speeds to produce offsets that affect the entire curve.

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. WebDesign Challenges of Analog-To-Digital Converters (ADC) 3 entire Nyquist region. There are a number of different implementations of dither, and each approach to dither impacts the overall ADC transfer function and performance differently. In order to simulate the impact of dither on the ADC performance, a transient noise simulation is required,
