Low Power Control IC for Efficient High-Voltage Piezoelectric
Driving in a Flying Robotic Insect

 

Abstract

A dual-channel, low power control IC for driving high voltage piezoelectric actuators in a flapping-wing robotic insect is presented. The IC controls milligram-scale power electronics that meet the stringent weight and power requirements of aerial microrobots. Designed in a 0.13 micron CMOS process, the IC implements an efficient control algorithm to drive piezoelectric actuators with high temporal resolution while consuming <100 microwatts during normal operation at 1.0V.
