Abstract
Summary In this letter, a third‐order wideband voltage‐mode all‐pass filter (APF) is proposed for application as a true time delay (TTD) cell. The advantages of designing a single‐stage higher order filter over cascading several lower order stages are illustrated. The proposed APF circuit is based on a single metal‐oxide‐semiconductor (MOS) transistor and is canonical because it requires one resistor, one inductor, and two capacitors. To the best of the authors' knowledge, this is the first single‐transistor third‐order APF circuit to be reported in the literature. The operation of the proposed APF is validated through post‐layout simulations in a 65‐nm CMOS technology. The simulation results demonstrate a group delay of 59.4 ps across a 13.2‐GHz bandwidth with a maximum delay‐bandwidth product of 0.783, while consuming only 3.54mW from a 1‐V supply voltage. Moreover, the designed circuit achieves an input‐referred IP3 of 19.95 dBm and occupies an area of 161.5 μ m × 204.8 μ m.

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
