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:
- Consider updating to the latest 2023b version of MATLAB.
- If unable to update, redefine the “ADC Testbench” block parameters in 2023a as shown below:
I hope this helps!
