I am doing quantization in optical domain. Is there any way to use builtin ADC just for sampling? As we can use builtin ADC as a quantizer if we make the sampling rate default but it is not working as just a sampler. Please Help.

      This is a double reply (for extra points!) that I also posted in the other topic. You could make the resolution a very large value to remove the quantization effect or use a different component like the Electrical Downsampler.

      Respected Damian the builtin ADC is not working for more than 6 bits of resolution. I think its the upper limit of resolution for it. Isn’t it?

        Nope, I don’t think there is a strict limit. I think in your project you are now being limited by the sample rate of your simulation. Because really the signal is digital being used in a computer simulation, so if you keep increasing the resolution of the ADC component you will reach the simulation limit. You can increase the simulation resolution by increasing the samples per bit.
