Abstract
Ion traps for quantum computers need high voltages to confine ions in an electrostatic potential. This work presents a high voltage current-feedback instrumentation amplifier, implemented in 130 nm-CMOS, that is fully functional at temperatures below 20 K and dissipates only 1.5 mW when powered with ±12 V. Since drain-extended MOS transistors cannot be used at cryogenic temperatures, high-voltage compliance is achieved by stacking low-voltage transistors. The high-frequency noise is below 8 nV/vHz to avoid ion heating. Flicker noise and offset is reduced by chopping of the input gain stages.
