Abstract
A reduced power consumption actuator drive circuit that includes separate circuit power paths for different portions of the signal spectrum for applications in which lower frequencies have high amplitudes. The low frequency circuit paths use higher power supply voltages at lower currents and the high frequency circuit paths use lower power supply voltages at higher currents. In one embodiment, the drive circuit drives a nutator that employs a resonating circuit that maintains actuator motion with reduced energy supplied by the power supply.
