Aradiation-hard, 130-Volt, 100-KHz capable, quad-channel operational amplifier with corresponding power supply and 6th-order Bessel filter circuitry has been designed, fabricated, and successfully tested. To control two-axis microelectromechanical systems (MEMS)-based mirrors, a differential high-voltage amplifier is required. The bandwidth of these mirrors is generally

The design has been fabricated and demonstrated to meet the requirements of the MEMS mirrors it is intended to control. This amplifier has application in any spaceflight mission requiring MEMS mirrors or high-bandwidth, high-voltage operational amplifiers.
