Engineering Tools

Interactive calculators and simulation models designed to assist hardware engineers in analyzing non-linearities, noise, and signal degradation.

Active Simulator

ADC Input Stage Simulator

An interactive simulator and design space explorer for analog-to-digital converter frontends. Simulates the physical impact of non-linear capacitor DC bias (MLCC Class II) and sampling switch settling dynamics on dynamic performance metrics (THD, SNR, SINAD, ENOB).

Stiff ODE Solver Support: Integrates coupled RC networks using implicit Radau and fast semi-implicit linearization algorithms.

Unified Component Library: Dynamically loads real capacitor parameters to model voltage-dependent capacitance drops.

Dynamic Loss Decomposition: Performs ablation analysis to isolate baseline floor, C(V) non-linearity, and settling errors.

Design Space Exploration: Sweeps parameters in N-dimensional space to output interactive Plotly heatmaps.
