A new differential CMOS current pre-amplifier for optical communications
Bibliographic record
Abstract
This paper presents a new low-voltage fully differential CMOS current-mode pre-amplifier for optical communications. The number of transistors between the power and ground rails is minimum so that the minimum supply voltage is only V/sub T/ + V/sub sat/. The pre-amplifier is a balanced two-stage configuration such that the effect of bias-dependent. mismatches is minimized. This configuration also achieves wide bandwidth and high current gain with reduced power consumption and transistor sizes. To lower the input impedance and increase the bandwidth, a new differential current-current negative feedback is introduced. In addition, a current-current common-mode feedback is employed to increase the common-mode rejection ratio (CMRR). The pre-amplifier is designed using a 0.18 /spl mu/m 1.8 V CMOS technology. Simulation results from SPICE demonstrate that with a 0.5 pF photo diode capacitance, the pre-amplifier provides 31 dB current gain or equivalently 65 dB trans-impedance gain at 2.53 GHz.

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.
