Abstract

See full text

A circuit for generating a voltage waveform at an output node. The circuit includes a voltage rail connected to the output node via a voltage rail switch; an anchor node connected to the output node via an inductor and a bidirectional switch, wherein the bidirectional switch includes two or more transistors connected in series; and a control unit configured to change the voltage at the output node by controlling the voltage rail switch and the bidirectional switch so that, if a load capacitance is connected to the output node, a resonant circuit is established between the inductor and the load capacitance. The circuit may be included in an apparatus for use in processing charged particles, e.g. for use in performing mass spectrometry or ion mobility spectrometry.
