A Design Methodology for Wideband Current-Reuse Receiver Front-Ends Aimed at Low-Power Applications
Bibliographic record
Abstract
This work gives a design perspective on low-power and wideband RF-to-Baseband current-reuse receivers (CRR). The proposed CRR architecture design shares a single supply and biasing current among both LNTA and baseband circuits to reduce power consumption. The work discusses topology selection and a suitable design procedure of the low noise transconductance amplifier (LNTA), down-conversion passive-mixer, active-inductor (AI) and TIA circuits. Layout considerations are also discussed. The receiver was simulated in 130 nm CMOS technology and occupies an active area of 0.025 mm2. It achieves a wideband input matching of less than −10 dB from 0.8 GHz to 3.4 GHz. A conversion-gain of 39.5 dB, IIP3 of −28 dBm and a double-sideband (DSB) NF of 5.6 dB is simulated at a local-oscillator (LO) frequency of 2.4 GHz and an intermediate frequency (IF) of 10 MHz, while consuming 1.92 mA from a 1.2 V supply.

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.
