Abstract
A dual-channel, low power control IC for driving highvoltage piezoelectric actuators in a flapping-wing robotic insect is presented. The IC controls milligram-scale power electronics that meet the stringent weight and power requirementsof aerial microrobots. Designed in a 0.13µm CMOS process,the IC implements an efficient control algorithm to drive piezoelectric actuators with high temporal resolution while consuming 100µW during normal operation at 1.0V.Keywords: low power, SOC, high voltage, piezoelectricactuator, and microrobotics.
