Ch21 Topic 08 - DAC Reconstruction Filter
=========================================

Purpose
-------
Filter zero-order-hold/staircase output components while preserving the required baseband bandwidth and settling time.

Open in RFspice
---------------
1. Open ACDSPICE_Ch21_T08_Reconstruction_Filter.rfspice.json.
2. Run the analysis already entered in the Analysis box.
3. Plot the nodes/currents named in expected_results.txt.
4. Compare with the hand calculation before changing values.

Files
-----
- ACDSPICE_Ch21_T08_Reconstruction_Filter.rfspice.json: native RFspice schematic/project JSON.
- ACDSPICE_Ch21_T08_Reconstruction_Filter.cir: corresponding plain SPICE netlist.
- expected_results.txt: expected checks and design trends.
- models/ACDSPICE_sensor_converter_models.lib: local educational model library.

Model note
----------
The supplied sensor, op-amp and switch models are educational and deliberately transparent. For hardware correlation, replace them with the selected sensor/output model, converter input/reference model and manufacturer op-amp model, then apply datasheet min/max limits and temperature/tolerance corners.
