Question 3 A switched capacitor inverter operating at 20 kHz with input voltage = 10V, is used to generate approximately -10V across a 10uF capacitor in parallel with a 10 k load. The flying" capacitor is 5 uF. a) Show that the voltage at the load will be closer to the desired -10V if the flying capacitor value is increased to 10uF by calculating the voltage across the load for both cases. (5 points) Hint: consider the effect of Req and recall that two switches are required to implement a voltage inverter. b) Explain the benefits of using a flying capacitor with a low ESR (5 points) Question 3 A switched capacitor inverter operating at 20 kHz with input voltage = 10V, is used to generate approximately -10V across a 10uF capacitor in parallel with a 10 k load.
