Find the least value of capacitors, average current drain from a battery.

Presume that we are designing a cardiac pacemaker circuit. The circuit is required to deliver pulses of 1-ms duration to the heart that can be modelled as a 500-? resistance. The peak amplitude of the pulses is required to be 5V. Though, the battery delivers only 2.5V. Therefore, we decide to charge two equal value capacitors in parallel from the 2.5-V battery and then switch the capacitors in series with the heart during the 1-ms pulse. What is the minimum value of the capacitors required so the output pulse amplitude remains between 4.9V and 5.0V throughout its 1-ms duration? If the pulses occur once a second, what is the average current drain from the battery? Utilize approximate calculations assuming constant current during the output pulse. Find out the ampere-hour rating of the battery so it lasts for five years.

Plan set of switches to satisfy the requirements of the circuit

Hint: use discharging mode to find capacitors and charging mode to find out average current.

Illustrate the circuits and plots for discharging and charging mode with ALL voltages indicated
