Tunable, low-power, high-gain Transimpedance amplifier for fNIRS photoreceiver front-end
Bibliographic record
Abstract
We present in this paper a new Transimpedance Amplifier (TIA) for photoreceiver front-end circuit designed using 0.35 μm CMOS technology to be used in a functional near infrared spectroscopy (fNIRS) system. The main advantages of this circuit are low-power consumption (0.01 mW and 0.3 mW at 1 V and 3 V bias voltages) and high transimpedance gain (0.1 to 250 MV/A) accompanying with the tunable high bandwidth (1 kHz to 1 GHz), high-speed data rate and very low input and output noise, 1 fA/√Hz and 2 μV/√Hz respectively. The post-layout simulation results confirm the excellent performance of the proposed design compared to latest available photoreceivers.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
