This prototype serves as a reconfigurable voltage and capacitance readout ASIC. It contains different analog and mixed signal blocks namely amplifiers, voltage reference, ADC and biasing circuitry in addition to the digital controller and SPI communication blocks. The chip design is flexible enough to allow for the characterization of the individual blocks yet still function as a whole system for early demonstrations.

This design flexibility and rapid prototyping (6 months, 1 engineer) was enabled by the support from EUROPRACTICE and the maturity of the XFAB technology library.

One application for this ASIC is the integration in a Systemin-in-Foil (SiF), where multiple electronic components are combined into a flexible substrate.

This tapeout was the first time for IMS CHIPS to participate in the mini@sic MPW run organized by EUROPRACTICE. For a design idea that requires a proof-of-concept hardware, mini@sic run was our best candidate. We were also interested to access the advanced technology nodes. It is remarkable how EUROPRACTICE makes them available. In addition, EUROPRACTICE representatives have shown a consistent support and professionalism starting from the early design kit installation until the tapeout and chip delivery.
