Question

Design a capacitive voltage divider that will have an output voltage of 50V when the input voltage is 0.5 MV. Assume that the input impedance magnitude is 50 Ohms when the frequency is 200 kHz. Will your design work for a DC input voltage? Will it work for really, really high frequencies? Your explanations should hook up the mathematics with what is happening physically in the circuit. Consider this argument: "The expression for Vout/Vin is independent of the frequency. This means that I can use the capacitive voltage divider at any frequency." How would you respond to this argument? Specifically, explain why the frequency matters even though it does not show up in the expression for Vout/Vin. The expression for the input impedance that you used in part (a) remains the same if you exchange C1 for C2. So, if we exchanged the two capacitances in the voltage divider, would that make a difference? Explain.
