摘要：

Scanning probe microscopies typically rely on coarse-approach slip-stick piezoelectric motors that work by exciting piezoelectric stacks with sawtooth signals of hundreds of V and some kHz. For this application, we introduce a single-polarity high-voltage amplifier based on discrete MOSFET-technology components with improved output current desirable for low-temperature actuation. The amplifier has an output signal of 600 V, 100 mA output current, noise level below 2 mu V/root Hz, 4 kHz high-voltage bandwidth, 2 V/mu s slew-rate, and rise and fall times of 80 mu s (when loaded with 30 nF). The circuit was successfully applied to drive a home-made scanning tunnelling microscope. (C) 2013 AIP Publishing LLC. [http://dx.doi.org/10.1063/1.4804166]
