Nanostructured CMOS Wireless Ultra-Wideband Label-Free PCR-Free DNA Analysis SoC
Bibliographic record
Abstract
A fully integrated 54-channel wireless fast-scan cyclic voltammetry DNA analysis SoC is presented. The microsystem includes 546 3D nanostructured and 54 2D gold DNA sensing microelectrodes as well as 54 pH sensors. Each channel consists of a chopper-stabilized current conveyer with dynamic element matching. It is utilized as the amperometric readout circuit with a linear resolution from 8.6 pA to 350 nA. The on-chip programmable waveform generator provides a wide range of user-controlled rate and amplitude parameters with a maximum scan range of 1.2 V, and scan rate ranging between 0.1 mV/sec to 300 V/sec. A digital ultra-wideband transmitter based on a delay line architecture provides wireless data communication with data rates of up to 50 Mb/sec while consuming 400 µW. The 3 mm × 3 mm prototype fabricated in a 0.13 µm standard CMOS technology has been validated in prostate cancer synthetic DNA detection with 10 aM label-free PCR-free detection limit. Each channel occupies an area of only 0.06 mm 2 and consumes 42 µW of power from a 1.2 V supply.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
