ADCToolbox

A Python toolbox for ADC characterization, calibration, modeling, and visualization.

ADCToolbox provides spectrum analysis, sine fitting, analog error diagnostics, digital bit-weight calibration, SAR behavioral models, time-interleaved ADC helpers, and ready-to-run examples.

Installation

pip install adctoolbox

Check the installed version:

python -c "import adctoolbox; print(adctoolbox.__version__)"

Quick Start

import numpy as np
from adctoolbox import analyze_spectrum, find_coherent_frequency

fs = 800e6
n_fft = 2**13
fin, _ = find_coherent_frequency(fs=fs, fin_target=80e6, n_fft=n_fft)

t = np.arange(n_fft) / fs
signal = 0.49 * np.sin(2 * np.pi * fin * t)

result = analyze_spectrum(signal, fs=fs, max_scale_range=(-0.5, 0.5))
print(f"ENOB: {result['enob']:.2f} bits")
print(f"SNDR: {result['sndr_dbc']:.2f} dBc")

Examples

Copy the full example tree into your workspace:

adctoolbox-get-examples
cd adctoolbox_examples
python 01_basic/exp_b01_environment_check.py
python 02_spectrum/exp_s01_analyze_spectrum_simplest.py

The package currently ships 59 runnable examples across spectrum analysis, signal generation, analog debug, digital calibration, toolset dashboards, unit conversions, time-interleaved ADC analysis, and subsample output behavior.

Common APIs

from adctoolbox import (
    analyze_spectrum,
    fit_sine_4param,
    analyze_error_pdf,
    analyze_error_by_phase,
    analyze_inl_from_sine,
    calibrate_weight_sine,
    sar_convert,
    sar_reconstruct,
    sar_apply_cap_mismatch,
)

Most modern APIs return dictionaries with stable snake_case keys. For example, analyze_spectrum(...) returns metrics such as enob, sndr_dbc, snr_dbc, sfdr_dbc, thd_dbc, sig_pwr_dbfs, and nsd_dbfs_hz.

Codex Skills

ADCToolbox also ships bundled Codex skills. Install them into an explicit destination:

adctoolbox-install-skill --dest ~/.codex/skills
adctoolbox-install-skill --status --dest ~/.codex/skills

For local skill development:

adctoolbox-install-skill --dev --editable --force --dest ~/.codex/skills
