Paper Abstract

We report on an application specific integrated circuit (ASIC) drive electronics system being developed for integration with low-voltage (~20 V) microelectromechanical (MEMS) deformable mirror technology for next- generation adaptive optics instruments. The ASIC is designed and manufactured using a CMOS foundry to address the power consumption and signal routing complexity issues inherent to conventional drive electronics. A prototype 9-channel driver capable of producing a bipolar (±15 V) output signal has been designed and sent for fabrication. Simulation results and preliminary integration avenues for a fully packaged ASIC/MEMS device that exploit increasingly popular trends in the semiconductor industry will also be presented.
