Abstract
A method of charge reuse, the method may include repeating the steps of: electrically coupling a first group of capacitive loads to a second group of capacitive loads; wherein the capacitive loads of the first group and of the second group are Microelectromechanical systems (MEMS) capacitive loads or Nanoelectromechanical systems (NEMS) capacitive loads; charging the second group with a first charge provided from the first group; electrically disconnecting the first group from the second group; operating the second group while using the first charge; electrically coupling the first group to the second group; charging the first group with a second charge provided from the second group; electrically disconnecting the first group from the second group; and operating the first group while using the second charge.
