The ±lter will have a Butterworth (Maximally Flat) transfer function. The Butterworth - 3dB corner frequency will be f c = 50kHz. Choose the resistors and capac- itors such that the integrated output noise of the ±lter is < 20 μ Vrms. Use SPICE to verify your design can meet these specs. Use a SPICE Voltage

Unformatted text preview: Controlled Voltage Source (VCVS) for the opamp. Run the AC simulation over the frequency range 10Hz to 10MHz with at least 100 points per decade. The noise is to be integrated over this entire frequency range. Give a complete labeled drawing of your schematic showing the value of all components. Give the simulation results in the form of plots of the magnitude of the transfer function and output noise versus frequency. Give your SPICE complete input ±le or your test bench circuit and netlist....
