Suppose that we are designing a cardiac pacemaker circuit. Thecircuit is required to deliver pulses of 1-ms duration to theheart, which can be modeled as a 500-Ω resistance. The peakamplitude of the pulses is required to be 5 V. However, the batterydelivers only 2.5 V. Therefore, we decide to charge two equal-valuecapacitors in parallel from the 2.5 V battery and then switch thecapacitors in series with the heart during the 1-ms pulse. What isthe minimum value of the capacitances required so the output pulseamplitude remains between 4.9 V and 5.0 V throughout its 1-msduration? If the pulses occur once every second, what is the average current drain from the battery? Use approximate calculations, assuming constant current during the output pulse.Find the ampere-hour rating of the battery so it lasts for five years.
