A Dual Loop Current Mode Feedback Capacitor Less LDO for High Current Applications
Bibliographic record
Abstract
This paper presents a high speed, high current, capacitor less analog low dropout (LDO) voltage regulator using a dual loop architecture. The voltage feedback coupled with current feedback loop regulating the output is utilized in the proposed design. The voltage feedback provides accurate voltage regulation while the current feedback provides the feature of fast response to wide load changes. A feedforward line filter is employed to improve the power supply rejection ratio (PSRR) by making use of an extra path that directly affects the voltage at the gate of the power transistor. The proposed LDO is designed in a TSMC 180-nm 1.8 V standard CMOS technology. The overall design occupies an active area of 0.0131 mm2and can supply up to 500 mA at 1.2 V output while supporting load capacitance from 0 to 2 nF. During a 500 mA step-load, the transient response time is 3.1 µs with overshoot and undershoot of 132 mV and 156 mV, respectively. The measured PSRR is -43.78 dB at 10 kHz and -23.70 dB at 1 MHz when the line filter is activated.

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.
