# Control-Bounded A/D Conversion (cbadc) Toolbox
This package is intended as a design tool for aiding the construction of control-bounded A/D converters.
Specifically, it is capable of:
- **Generating** transfer functions for analog systems and/or digital estimator parametrizations.
- **Estimating** samples from control signals.
- **Simulating** analog system and digital control interactions.
# Documentation
The projects official documentation can be found at [Read the Docs](https://cbadc.readthedocs.io/en/latest/).

# Changelog
## 0.2.0
Major structural changes. Mainly motivated by improving simulators and filter coefficient computations to support switch-cap digital control simulations.
Specifically,
- [digital clock](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.analog_signal.clock.Clock.html#cbadc.analog_signal.clock.Clock) to aid the simulator and digital estimator computation
- [digital control](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.digital_control.digital_control.DigitalControl.html#cbadc.digital_control.digital_control.DigitalControl) and derived classes have a new interface to support [digital clock](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.analog_signal.clock.Clock.html#cbadc.analog_signal.clock.Clock), i.e, `DigitalControl(..., clock, ...)`.
- [Simulator](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.simulator.html)
- [Analytical simulator](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.simulator.analytical_simulator.AnalyticalSimulator.html#cbadc.simulator.analytical_simulator.AnalyticalSimulator) implemented using [SymPy](https://www.sympy.org/en/index.html)
- [Mpmath simulator](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.simulator.mp_simulator.MPSimulator.html#cbadc.simulator.mp_simulator.MPSimulator) implemented using [mpmath](https://mpmath.org)
- Two Numerical simulators implemented using [NumPy](https://numpy.org)
- [Full simulator](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.simulator.numerical_simulator.FullSimulator.html#cbadc.simulator.numerical_simulator.FullSimulator) the pervious default simulator.
- [pre-computed simulator](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.simulator.numerical_simulator.PreComputedControlSignalsSimulator.html) same as Full simulator with the distinction that the control contributions are pre-computed.
- The previous default [StateSpaceSimulator class](https://cbadc.readthedocs.io/en/v0.1.0/api/autosummary/cbadc.simulator.StateSpaceSimulator.html#cbadc.simulator.StateSpaceSimulator) has been replaced by the [`get_simulator`](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.simulator.wrapper.get_simulator.html#cbadc.simulator.wrapper.get_simulator) function. The simulation backend is chosen by passing an instance of [SimulatorType]().
- The simulation clock period Ts is replaced by the [digital clock]() object and thus all simulator classes and the factory function `get_simulation(..., clock, ...)` is now instantiated with a clock determining the sample times.
- [DigitalEstimator](https://cbadc.readthedocs.io/en/v0.1.0/api/autosummary/cbadc.digital_estimator.DigitalEstimator.html#cbadc.digital_estimator.DigitalEstimator)
- The default DigitalEstimator changes it's name to [BatchEstimator](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.digital_estimator.batch_estimator.BatchEstimator.html#cbadc.digital_estimator.batch_estimator.BatchEstimator)
- an additional filter computation backend implemented with [mpmath](https://mpmath.org)
- Improved care implementation using [SymPy](https://www.sympy.org/en/index.html) instead of [SciPy](https://scipy.org).
- `cbadc.specification.get_chain_of_integrator` and `cbadc.specification.get_leap_frog` a computation aid to dimension chain-of-integrators and leap-frog analog-frontends to meet ENOB and BW specifications
Added verilog-ams circuit-level submodule
Such that circuit-level implementations can be
- constructed in Verilog-ams
- the resulting filter coefficients can be computed
- the resulting analog frontends can be simulated.
### 0.1.5
Added figures of merit [fom](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.fom.html#module-cbadc.fom) modul, [MurmannSurvey](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.fom.MurmannSurvey.html#cbadc.fom.MurmannSurvey) convenience class, and a new tutorial [The Murmann ADC Survey](https://cbadc.readthedocs.io/en/latest/tutorials/c_further/plot_a_Murmann_ADC_survey.html#sphx-glr-tutorials-c-further-plot-a-murmann-adc-survey-py).
### 0.1.2
Added fixed point arithmetics for FIR filter implementation.
### 0.1.1
Added support for switched capacitor digital control by adding a new:
- [simulator](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.simulator.SwitchedCapacitorStateSpaceSimulator.html#cbadc.simulator.SwitchedCapacitorStateSpaceSimulator),
- [digital control](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.digital_control.SwitchedCapacitorControl.html#cbadc.digital_control.SwitchedCapacitorControl),
- and modifications to the FIR [digital estimator](https://cbadc.readthedocs.io/en/latest/api/autosummary/cbadc.digital_estimator.FIRFilter.html#cbadc.digital_estimator.FIRFilter) to handle the switch cap case.
