A dual-band CMOS VCO for automotive radar using a new negative resistance circuitry
Bibliographic record
Abstract
A novel structure of negative resistance circuit is presented. Using this structure, we develop a dual-band differential voltage controlled oscillator (VCO) for automotive radar. The proposed negative resistance circuit allows the use of the bias tail resistor that increases the oscillation voltage headroom, and improves the phase noise performance of the VCO. Moreover, this structure shows low parasitic capacitance resulting in a wide frequency tuning range. The proposed VCO is implemented in TSMC 65 nm CMOS technology. Post-layout simulation results show tuning ranges of 22-27 GHz and 74-81 GHz for the 24 and 77 GHz bands, respectively. The phase noises at the offset of 1 MHz are less than -127 and -114dBc/Hz for 24 and 77 GHz bands, respectively.

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.
