Model of the month

Modeling delta-sigma D/A converters

This application note demonstrates models of various delta-sigma D/A converters and testbenches to simulate their transient, DC, and AC characteristics.

Tip of the Month

Generating a clock with the phase noise of a PLL

Now that you've learned how to shape the phase noise of a clock using an arbitrary transfer function, can you generate a clock that has the phase noise characteristics of a phase-locked loop (PLL)?

Primitive of the Month

clk_to_phase

This primitive outputs the phase of the input clock.
