What is it about?
High speed nanopositioning applications require high speed nanopositioners as well as the electronic amplifiers to drive them. High-speed and high resonance piezos are often used in these applications. However, such piezos generally have high electrical capacitance. This high capacitance often leads to low bandwidths in combination with traditional high-voltage amplifiers. In this paper, we present a high-voltage amplifier structure that circumvents this problem.
