A new fully integrated CMOS interface for a dielectrophoretic lab-on-a-chip device
Bibliographic record
Abstract
We present in this paper a new CMOS interface for cell manipulation by dielectrophoresis and capacitive sensing system dedicated for a lab-on-a-chip. It fully integrates a signal generation circuit and a post-processing system to control parameters of each signal such as frequency, phase and amplitude. In addition, a large capacitive and low resistive load driver circuit is designed to deliver a current of 9 mA for each 16 electrodes as the microfluidic architecture is divided into 4 blocs containing 16 electrodes each one. Thus, the proposed CMOS chip provides 4-channel signals with individually controllable phase and amplitude. In addition, a capacitive sensing system has been integrated into the same chip to detect the capacitive change in the microchannel in the Lab-on-a-chip. The generated signals have a 2.5 peak-to-peak voltage range and 70 kHz frequency range while the detection system has a dynamic range of 1.5 V and a sensitivity of 11.8 fF/V.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
