Analysis of integer-N phase-locked-loop architecture
Bibliographic record
Abstract
Phase-Locked Loops have a wide range of applications as frequency synthesizers. An analysis of Integer-N Phase-Locked-Loop (PLL) is presented in this article. The performance of a phase-locked loop is determined by a number of factors. It is shown whether good locking time performance can be provided by changing the loop bandwidth of the PLL system. The loop filter can be designed to accelerate the lock time because it controls the poles and zeros of the system. The PLL system is a typical Charge-Pump PLL which uses a Ring Voltage-Controlled Oscillator (Ring-VCO) to optimize the area as much as possible and to reduce power consumption. The phase noise of the Ring-VCO at 1MHz is -96.14dBc and the system can deliver a stable output frequency of 1.6GHz with a 100MHz reference clock. The Multi-Modulus Divider (MMD) used can provide divider ratios from 16 to 31. Simulation is done by TSMC 40nm process.

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.
