Abstract
Digital isolators are implemented to protect low-voltage electronics and ensure human safety during high-voltage surge events. In this work, we present the design of an inductive-based digital isolation system that can sustain up to 1 kVrms breakdown voltage. The proposed system is designed using the pulse polarity modulation scheme and fabricated in a 0.35 μm CMOS. Two identical dies are bounded within the IC package, with one die housing the transmitter (Tx) and the isolation transformer, while the other die contains the receiver (Rx). Two different customized designs between three metal layers are implemented to form the isolation element. The transformer’s secondary coil is constructed in metal-1, while the primary coil is formed in metal-2 and metal-3 for comparing the system functionality, isolation capability, and propagation delay. The functionality has been verified by measurements for an operating frequency of 300 MHz with a 2.6 ns propagation delay and an energy consumption of 8.15 × 103 pJ/bit at 1 Mbps. The chip was tested under extreme temperatures and achieved a maximum measured common mode transient immunity (CMTI) of 500 V/μs. Jitter has been examined to ensure fast transmission at a bit error rate (BER) of 10−15 with a total jitter (TJ) of 188.18 ps.

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 it
