Verilog-A filters are analog operators that remove some unwanted components or features from a signal. Similar to functions, filters take arguments at the input and return a value. However, as with other Verilog-A analog operators, filters also maintain their internal states and their output is a function of both the input arguments and the internal states. Verilog-A supports filters in the time and frequency domain.
Time-Domain Filters
Verilog-A provides a set of time-domain filters that can be used to delay signals and to remove discontinuity or bound rate ...
