Abstract
This article discusses a kind of Digital Ion Trap Mass Spectrometry. This system is based on the DSP/MCU controllers and a D/A converter and a special transformer and a power amplifier and an avalanche photodetector. It can get a higher precision and very exact voltage for measurement. Because it changes low voltage to ±250V in the end by transformer and no switches to turn on and turn off, therefore there is no EMI/EMC disturbs, and system has a small volume. We also can make a higher voltage system such as ±1000V or ±2000V following the method we discussed below.
