A power-efficient dual-tank FSK demodulator for passive wireless microsystems
Bibliographic record
Abstract
A dual-tank FSK demodulator to boost the amplitude of the received signal at FSK carrier frequencies subsequently power conversion efficiency is presented. A fast energy depletion technique is proposed to increase the data rate. In addition, a full-wave quadruple voltage multiplier with low substrate leakage currents is proposed to produce dual-polarity supply voltages required for draining the resonant tanks. Data are recovered by comparing output voltages of the resonant tanks with a preset reference voltage at the beginning of each FSK interval. The FSK demodulator has been designed in IBM 0.13-μm 1.2-V CMOS process. Simulation results show that the power conversion efficiency of the proposed dual-tank voltage multiplier is 30 times that of a corresponding single-tank voltage multiplier while the substrate leakage current of the proposed voltage multiplier is nearly 1000 times smaller than that of conventional voltage multipliers. The proposed FSK demodulator can transmit at 3 Mbps with 5/10-MHz FSK carriers while consuming only a few tens of μW.

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.
