- Abstract
- Monitoring microbial electrochemical processes in a time-and cost-efficient manner requires multi-channel potentiostats with the capability to control each channel towards a unique targeted potential. State-of-the-art (SotA) PCB potentiostats cannot perform high-frequency analysis due to their limited bandwidth. Existing integrated CMOS potentiostats on the other hand enable higher sensing channel density with a high bandwidth, yet are still limited in the number of parallel stimulation channels. The presented 40nm CMOS potentiostat chip overcomes this bottleneck with 96 individually controllable stimulation and sensing channels with a wide 12 pA - 137 mu A current range and up to 3 MHz bandwidth. The architecture is optimized for area-efficiency and includes a digital feedback controller integrated on-chip, supporting multi-functional electrochemical analysis techniques. Fully parallel operation is demonstrated for a (bio-)electrochemical measurement.
