View attachment SC 5th Order Butterworth - Bode.pdf The resulting Bode Plot is nothing like a LPF: View attachment SC 5th Order Butterworth - Circuit - Inverting Switch Block 2.pdf View attachment SC 5th Order Butterworth - Circuit - Inverting Switch Block.pdf With the heirachal inverting blocks implemented like so: View attachment SC 5th Order Butterworth - Circuit.pdf The circuit looks like so (note all components are Ideal): I am trying to replicate a design used in "Design with Operational Amplifiers and Analog Integrated Circuits" by Sergio Franco in Figure 4.33 using Ideal components, where the component values have been worked out in Example 4.13 for f_c = 1kHz at a f_ck = 100kHz and providing the following capacitor values:Ĭ_Ri = C_Ro = C_0 = 1pF, C_C1 = C_C5 = 9.84pF, C_L2 = C_L4 = 25.75pF, and C_C3 = 31.83pF. What types of applications can this circuit be used in? Explain.I am wondering if someone could help me with designing a 5th Order Butterworth LPF using a Switching Capacitor topology in NI Multisim 13.0? Record measured values and calculations in this section. Show all screen shots – that prove all meter readings. Using bode plotter cursor to mark and measure the low and high cutoff frequency, calculate the bandwidth. How does the calculated voltage gain compare to the midband gain from the Bode plot? Record both values in the results section, and use them to calculate the voltage gain in decibel – show ALL work. Set the function generator amplitude to 5mVp and 10Hz.Īttach the Tektronix oscilloscope channel 1 to measure peak-to-peak voltage across the function generator, and channel 2 to measure the peak-to-peak voltage across the load RL. Using Multisim construct the circuits shown below:Ĭonnect the Bode Plotter as shown, and use the setting in the figure. What are Bode plots? Use a well labelled diagram to aid your explanation.Ĭalculate the input-coupling circuit and output-coupling circuit low-frequency cutoff points for the circuit shown below.
