The proposed mixed-signal feedback loop for tripolar cuff electrode imbalance compensation provides an interference rejection of 56 dB with a negligible power overhead.

To do this we use FDSOI devices fabricated with 2-metal gate levels in an industry-compatible CMOS process. We operate them at 100mK, and in a dot-configuration where large control on tunnel barriers is leveraged. In the many-electron regime, we observe the transition of quantum dot array from single- to triple-dot configurations.
