A low current CMOS voltage regulator including RF desensitization for RFIC power amplifiers
Bibliographic record
Abstract
This paper presents a CMOS voltage regulator employing an operational-amplifier operated from a 1.8V supply with very low current consumption, capable of delivering a stable regulated 1.4V output voltage with high enough current sourcing capability for the biasing of GaAs HBT RFIC power amplifiers, and subjected to strong RF perturbations. These features are particularly important in multi-technology RFIC power amplifier modules requiring advanced CMOS control functions for efficiency and linearity performance improvement, but having minimal RF signal isolation between the RF amplifier IC and the CMOS control IC, for compactness and cost considerations. The regulator design uses a recycled folded cascode operational-amplifier structure in a CMOS 0.18μm technology. The results presented show a total bias current of 135μA for the operational-amplifier, a current sourcing capability of 20mA when delivered to the equivalent load seen at the base of a power GaAs HBT RF transistor under 1.88GHz-20dBm excitation, and a drop of only 40mV in the regulated output voltage (97% regulation) when using an RF isolation inductor as small as 6nH.

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.
