Modeling a digital low-dropout (LDO) regulator
This application note explains how to model a basic digital LDO and simulate its line, load, reference transient and DC/AC regulation characteristics.

For high-pass filters, the 'gain' parameter of the 'filter' primitive does not directly define the passband gain. This Q&A post explains how to set its parameters correctly.
This core primitive of XMODEL can model a linear filter with arbitrary numbers of poles and zeros.
