A wide-band high-voltage monolithic amplifier

A monolithic amplifier capable of 80-V swing and 1.7-V/NS slew rate has been fabricated using standard integrated circuit techniques. The amplifier is intended for capacitive loads such as in electrostatic deflection applications. The totem-pole technique is combined with active feedback to produce this large voltage swing without excessive power consumption. A new output circuit linked with a floating current source is used to supply large accurate positive and negative charging currents over a large dynamic range. The amplifier voltage range is extendable by increasing the degree of stacking in the totem-pole arrangement.
