Abstract
<p>In this thesis, several novel circuits for use in an ultra-low power integer-n frequency synthesizer operating in the 402 MHz to 405 MHz Medical Implant Communication Service spectrum have been proposed. The proposed designs include a current-reuse quadrature voltage-controlled oscillator, a novel subthreshold source-coupled logic D-latch with clear and preset functionality, a programmable frequency divider and phase/frequency detector based on the aforementioned D-latch, and a modified current-steering charge pump. A design methodology for low-power CMOS oscillators was proposed based on the MOS EKV model and g<sub>m</sub>/i<sub>d</sub> design methodology. The proposed designs were implemented using IBM CMRF8SF130 nm CMOS technology and simulated using Cadence Spectre. Simulation results for the proposed current-reuse quadrature voltage-controlled oscillator and programmable frequency divider consume 420µW and 200µW respectively from a 0.7 V supply, a significant improvement compared to existing designs. The simulated phase noise of the proposed oscillator is -127.2 dBc/Hz at a 1 MHz offset. Measurement results from a fabricated prototype of the current-reuse quadrature verify the simulation results and serve as a proof-of-concept for the proposed design. The proposed designs were used to implement an integer-n frequency synthesizer and were submitted for fabrication. Simulation results show that the synthesizer consumes 635µW from a 0.7 V supply and has a locking time of 250µs.</p>

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.
