Suppose that we are designing a cardiac pacemaker circuit. Thecircuit is required to deliver pulses of 1-ms durstion to the heartthat can be modeled as a 500-Ω resistance. The peak amplitudeof the pulses is required to be 5 V. However, the battery deliversonly 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 1-ms puls. What is theminimum value of the capacitors required so the output pulseamplitude remains between 4.9 V and 5.0 V throughout its 1-msduration? If the pulses occur once a second, what is the averagecurrent drain from the battery, Use approximate calculationsassuming constant current during the output pulse. Find theampere-hour rating of the battery so its lasts for five years.
