Brief Study of Dither C: Dithered DNL

InĀ ‘Dither’ series B, I have shown dither reduces the harmonic distortion by decolalizing the code mapping of the analog signal from the transfer curve. So if we take a step further, we might say the main purpose of dither is … Continue reading

Brief Study of Dither B: Dither

In ‘Dither’ series A, I mentioned that the quantization will introduce large harmonics to a low-level sinusoidal signal. Let’s look at another example in Figure 1 [1]. Adding dither to the circuit means adding noise to the circuit. Now let’s … Continue reading

ADC Performance A : DNL vs. SNR

Recently I pick up Wang Xiaobo‘s essays again. One sentence from him made a deep impression on me: do what you like is ‘have’; do what you don’t know why you are doing is ‘not have’. Then I came here … Continue reading
