如果APB2为72MHz，这ADC CLK＝72MHz/2, /4, /6或/8 2.这里设的sample time是不是ADC转换一次...
I am trying to understand the Sample Time and Conversion Time for the K64 ADC as described in 35.4.4.5 Sample time and total conversion time. Consider a simple example case: CFG1[ADLPC] = 0 (normal power configuration)CFG1[ADIV] = 00 (divide ratio is 1, ADCK rate is the Bus Clock...

Sample-time error between channels degrades the resolution of time-interleaved analog-to-digital converters (TIADCs). A calibration method implemented in mixed circuits with low complexity and fast convergence is proposed in this paper. The algorithm for detecting sample-time error is based on correl...
I'm using ESP-IDF 5.2.1, and code is based on "examples\peripherals\adc\continuous_read". It appears to me that the actual ADC sample rate - that is, the amount of generated data in a given time interval - is off by a factor of 0.8181. This looks suspiciously (conjecture!) like ...
After a sampling event has been triggered by the ADCC controller, there is a conversion time latency associated with the ADC operation itself. This is shown in Figure 9 for a situation in which a single ADC event is associated with each ADC interface, and simultaneous sampling of the two eve...
When a non-DC signal is applied to the input of an ADC, it is changing amplitude continuously. However, the analog-to-digital conversion process takes a finite interval of time, so over that time, the amplitude of the ADC input will change (Figure 1). It is this amplitude skewing that...
