1. This HTML is a complete interactive datasheet. The underlying proprietary machine learning models were used to generate structured response grids for selected geometry presets, and those response grids are embedded here for fast local exploration without exposing the internal model implementation.
2. The geometric design variables are represented as curated presets rather than free sliders. That keeps the file responsive while preserving model fidelity where it matters most operationally: corner, AVDD, temperature, and VCNT.
3. The provided phase-noise models are at 1M, 10M, and 100M offsets. This datasheet therefore shows a three-point phase-noise curve rather than a continuous close-in phase-noise spectrum.
Purpose. This file lets a design engineer explore a 28nm VCO operating space interactively using embedded response data generated from AID proprietary machine learning models. It is intended for design exploration, tradeoff analysis, and pre-characterization planning. Final product release still requires signoff simulation and silicon validation.
1. Left-side Controls panel. Start here. Select the Preset Geometry, process corner, AVDD, temperature, and VCNT. Every KPI, chart, table, optimizer result, and design-tool view is tied to these controls. When any control changes, the datasheet recalculates the current operating point.
2. Preset Geometry selector. A preset is a fixed transistor/bias geometry family, including the hidden W/L and r1 values. Use it to compare design families such as balanced, lower-power, higher-performance, or wider-range configurations. The geometry box shows the active preset values, and the comparison table shows how all presets perform under the current AVDD, VCNT, temperature, and corner.
3. KPI cards. The cards at the top show the current operating point: frequency, AVDD power, ring current, and FoM at the 1M offset. Use these as the fastest check after moving any slider. For phase noise and deeper tradeoff details, use the Phase Noise and Design Tools tabs.
4. Overview tab. Use this tab for a compact summary of the selected point. The Live operating point table reports frequency, power, current, CCO voltage, and phase noise at 1M/10M/100M. The Model-quality summary reports validation metrics derived from the uploaded testing data. The Current preset at nominal conditions table gives a consistent reference point for comparing presets.
5. Charts tab. Use this tab to understand basic VCO behavior. Frequency vs VCNT shows tuning range. Power vs VCNT shows the power cost of tuning. Ring Current vs VCNT shows current trajectory. CCO Voltage vs VCNT shows the internal control-node proxy. Frequency heatmap shows the combined effect of AVDD and VCNT. Sensitivity snapshot quantifies local sensitivity to VCNT, AVDD, and temperature.
6. Phase Noise tab. Use this tab to evaluate RF noise behavior. Phase noise vs offset plots the available phase-noise predictions at 1M, 10M, and 100M on a logarithmic offset axis. Phase noise @ 1M vs VCNT shows how noise changes across the tuning range. PVT corner comparison shows frequency spread by corner at the selected operating point. Tradeoff cloud shows broader power/frequency/phase-noise relationships across sampled model-space points.
7. AI Query tab. Use this tab for inverse design. Set a target frequency, maximum power, frequency tolerance, objective, and search scope. Then press Run optimizer. The optimizer returns the best operating point found in the embedded library. Use Use current frequency as target when you want to optimize around the point currently selected by the left-side controls.
8. AI Query search scope. Choose Use current left-panel preset/corner/AVDD/temperature; sweep VCNT when you want a local operating-point recommendation. Choose Use current corner/AVDD/temperature; search all presets and VCNT when geometry may change but environment is fixed. Choose Search full embedded model library for the broadest exploration across presets, corners, AVDD, temperature, and VCNT.
9. Design Tools tab. Use this tab for design decision-making. Optimizer summary reports the active or recommended point. PN–Power tradeoff explorer shows whether lower phase noise requires more power. Kvco and tuning linearity shows df/dVCNT and helps identify the usable PLL tuning region. PVT robustness viewer shows how frequency, power, and phase noise move across available corners and temperatures. What-if sensitivity quantifies the impact of common perturbations around the current point.
10. Spec Tables tab. Use this tab to verify operating limits. Model domain lists the supported ranges from the uploaded data and range workbook. Do not extrapolate conclusions outside these ranges. Preset geometry table documents the W/L and r1 values used by each geometry preset embedded in this HTML.
11. Recommended design workflow. First select a preset and nominal environment. Next inspect frequency tuning in the Charts tab. Then check phase noise at 1M/10M/100M. Use AI Query to find candidate operating points. Finally use Design Tools to review PN-power tradeoff, Kvco linearity, PVT robustness, and what-if sensitivity before choosing a design point for SPICE confirmation.
12. Important limitation. The uploaded phase-noise data used here contains only 1M, 10M, and 100M offset predictions. This datasheet does not claim close-in phase noise below 1M offset, nor does it generate a continuous phase-noise spectrum unless additional model data is provided.
