- Consider updating to the latest 2023b version of MATLAB.
- If unable to update, redefine the “ADC Testbench” block parameters in 2023a as shown below:
使用matlab提供的SAR ADC模块,idea adc和analog adc用ac testbench跑出来的参数一模一样

我所使用的matlab版本是2023a,不知道为什么理想adc和模拟adc的参数一模一样。
这个例子来自于matlab中的Design and Evaluate Successive Approximation ADC Using Stateflow - MATLAB & Simulink - MathWorks 中国
我看《逐次逼近模/数(SAR ADC) 仿真与设计》一书中写道,这个模拟SAR ADC的有效位数是11
我在同学的电脑上用2020a版本的matlab跑出来的仿真就和这个书中一致,并不是我所跑出来的有效位数是9

你好,
我将用英语回答。
I understand you are trying to simulate the example “Design and Evaluate Successive Approximation ADC Using Stateflow” in 2023a version of MATLAB.
The example yields the expected ENOB value of 11 in the latest 2023b version of MATLAB. The likely reason is a change in the default values of the “Analog stimulus frequency” and “Resolution bandwidth” of the “ADC Testbench” block. To obtain the required ENOB of 11 in the referred example:
I hope this helps!
