View attachment SC 5th Order Butterworth - Clock.pdfĬan Switched Capacitor circuits be simulated in NI Multisim 13.0?Īs it is, I had a convergence problem and needed to relax ABSTOL to 1e-008A and VNTOL to 0.0001V in order to simulate the results. In the OUT portion of the file, plan to plot S 11 on a grid and Smith charts. Run an open-loop Bode plot at full load, lowest input 2. Someone had mentioned that because the convergence is being done at specific points in time, that a switched capacitor system might not be able to simulate correctly, and especially wouldn't bode plot correctly.Įventually I want to implement this circuit topology with a 7th Order Butterworth and a clock that is upwards of 10MHz, but for the present, I would be satisfied with just getting this circuit to work as expected. widths (approx 100nm) usually not a design issue Bode plot (frequency vs. Identify the excess/deficiency of gain at the selected cross over 3. Place a double zero at f 0, a pole at the ESR zero and a pole at F sw/2 4.
