    A linear amplifier capable of providing a single-ended output in excess of 3 kV across a predominantly capacitive load requiring charge/discharge currents of order 10 mA is described. High-voltage capability, low-power consumption and excellent linearity and harmonic distortion performance are all obtained from a simple circuit, employing negative voltage feedback around a high-voltage low-power MOSFET ladder. Results are presented which highlight the performance of the amplifier in its intended role as a triangular-wave voltage driver for an electro-optic crystal.
