A new CMOS tunable transconductor dedicated to VHF continuous-time filters
Bibliographic record
Abstract
A new CMOS transconductance (Gm) circuit with voltage-tunability and very wide bandwidth is proposed and analysed. The transconductance circuit is then used to realize a tunable VHF 2nd-order bandpass filter cell. The center frequency (f0) of the designed filter can be tuned by varying the transconductance value (gm) of the tunable Gm circuit. Simulation results indicate the excellent performances of both the transconductance circuit and the filter over a wideband range. The transconductance value can be tuned from 40 /spl mu/S to 950 /spl mu/S (490 /spl mu/S) and the filter center frequency (f0) in the range 30 MHz (4 MHz)-110 MHz (49 MHz) for /spl plusmn/2.5 V (/spl plusmn/1.5 V) supply voltages.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
