 Below, the clock waveforms are shown. As seen, the sampling phase ends when `clk_samp` goes low, which then triggers the comparator. This firing of the comparator generates a rising edge on `clk_algo`, initiating the SAR conversion. Since the `reset (rst)` signal is connected to the sampling clock and `Enable (En)` is tied to `Vdd` (i.e., always logic high), the SAR logic responds to the `clk_algo` signal (the output of the NAND gate) and begins the bit-wise comparison process.

 At this point, we have a working SAR ADC, so the primary tutorial goal is achieved. However, we will now extend the analysis by extracting the output and post-processing it in Python to recover the ADC's differential input waveform.

 ## Conclusion
 
 This post-processing step demonstrates how to extract and visualize the SAR ADC output. The setup also forms a solid foundation for further analysis, such as computing dynamic performance metrics of the ADC—SNR, SINAD, and ENOB—using standard Python libraries.
