Fully Integrated Dual-Channel Gate Driver and Area Efficient PID Compensator for Surge Tolerant Power Sensor Interface
Bibliographic record
Abstract
This paper presents a power sensor interface (PSI) driving a wide range of load valves with coil resistance ranging from 5 Ω to 62.5 Ω. It can sustain voltage surges up to 115 V. An integrated high-voltage (HV) dual-channel gate driver with 8.7 ns deadtime (DT) is implemented to efficiently drive e-GaN FETs in a synchronous DC-DC buck converter. In addition, an area-optimization technique of on-chip passive components is proposed to enable full-integration of voltage-mode controller with 87% reduction in area. The achieved peak efficiency is 98.7% @ 4.67 A load. The feedback bandwidth is ~100 kHz to maintain fast transient response at 1MHz switching frequency. The settling time is <; 70 μs and <; 100 μs at load changes of -5.2 A and 5.2 A respectively. Overshoot (OS) and undershoot (US) voltages are within 2% of nominal V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">OUT</sub> . The layout of the gate driver and feedback control is implemented in 0.35-μm HV CMOS process with active die area of 0.75 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .

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.
