1. A device for controlling trapped ions, the device comprising:
an ion trap;
a plurality of field electrodes configured to control ions in the ion trap; and
a controller chip electrically connected to the field electrodes, the controller chip comprising at least one delta-sigma digital to analog converter (DS-DAC) module comprising a DS-DAC circuit configured to:
receive a digital data stream;
convert the digital data stream to analog control voltages; and
supply the analog control voltages to the field electrodes.
