Reconfigurable PCM GeTe-Based Latching 6-Bit Digital Switched Capacitor Bank
Bibliographic record
Abstract
This paper reports the design, fabrication and characterization of a miniature RF phase change material (PCM) germanium telluride (GeTe) based 6-bit switched capacitor bank. The capacitor bank utilizes six latching PCM RF series switches, monolithically integrated with six metal-insulator-metal (MIM) capacitors, providing 64-states in a compact 0.5 mm × 0.5 mm package including the pads of the CPW input port and the control pads. The core measures only 0.23 mm × 0.27 mm making it a highly miniaturized and versatile switched capacitor bank for integrating with various RF circuits. Measured capacitance tuning range exhibits 34:1 at 2 GHz and 58:1 at 7 GHz with no self-resonance observed up to 7 GHz. The integrated RF PCM switches exhibit excellent RF performance with insertion loss lower than 0.2 dB and isolation better than 30 dB over 2 GHz to 7 GHz band. The proposed device is realized using seven-layer microfabrication process that includes a thermally conductive dielectric for efficient heat transportation. EM simulations and measurements demonstrate various states covering the capacitance range of 0.14 pF to 8 pF.

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.
