A Dual Frequency Compensation Technique to Improve Stability and Transient Response for a Three Stage Low-Drop-Out Linear Regulator
Bibliographic record
Abstract
A novel internal compensation technique named dual frequency compensation is proposed to improve the stability and the transient response of the on-chip output capacitor three stage low-drop-out linear voltage regulator (LDO). It exploits a combination of amplification and differentiation to sufficiently separate the dominant pole from the first non-dominant pole so that the latter is located after the unity gain frequency regardless of the load current value. The proposed LDO regulator is analyzed, designed, and simulated in standard 0.18 µm low voltage CMOS technology. The presented LDO regulator delivers a stable voltage of 1.2 V for an input supply voltage range of 1.35-1.85 V with a maximum line deviation of 4.68mV/V and can supply up to 150mA of the load current. The maximum transient variation of the output voltage is 54.5 mV when the load current pulses from 150mA to 0mA during a fall time of 1µs. The proposed LDO regulator has a low figure of merit compared with recent LDO regulators.

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.
