An 800 kS/s 1.83 fJ/conv. 12b ADC via Voltage Successive Approximation and Gated Cyclic Vernier Time Digitization
Bibliographic record
Abstract
A 12b analog-to-digital converter (ADC) consisting of an 8b successive approximation register (SAR) ADC, a voltage-to-time converter (VTC), and a gated cyclic Vernier time-to-digital converter (TDC) is presented. A number of design techniques including a sub-threshold delay-locked loop (DLL) with pulsed outputs to generate the clock signals of the ADC, a power/area-efficient technique to eliminate the kickback-induced errors of the comparator, a gated cyclic Vernier TDC to eliminate resolution loss at both input injection and catch, a self-resetting arbiter, and a power/area-efficient synchronous SAR are proposed. The ADC is designed in a TSMC 130 nm CMOS technology with a reduced supply voltage of 0.8 V. The simulation results of the ADC with a 7.42 kHz 400 ∼ 800 V differential sinusoidal input voltage show that at 800 kS/s, the ADC offers 59.32 dB SNDR and 9.56 ENOB while consuming 3.44 µW, yielding 1.83 fJ/conv. FOM.

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.
