Promising sensors inside ingestible solutions are the ion-sensitive field-effect transistor (ISFET) and chemical field-effect transistor (chemFET). When properly biased, these sensors translate an (electro)chemical modality into an electrical modality. To enable sensor operation and bridge the gap between the sensor and ADC, an analog front-end is needed. Since ingestible systems have a limited power budget, limiting power consumption is a must, and the typical large current biasing of these sensors must be questioned.
After studying the current literature on ultra-low power ISFET readouts, the first goal is to envision an appropriate architecture that fits the requirements and alleviates the problems that come with previous ultra-low power implementation. Secondly, a transistor level design and verification cycle will concretize the front-end. Lastly, layout of the transistor level schematic will prepare the front-end for a potential tape-out.
For ISFET experiments you will have access to our electronic lab. For design, verification, and layout we use the industry standard tools (Cadence Virtuoso, Mentor Graphics Calibre) and have high computational power servers available.
