Primitive of the Month

probe_dc

This primitive lets you measure the DC transfer function of your circuit model in a single simulation run.

Tip of the Month

Simulating the DC transfer characteristics of a circuit model

Learn how to perform DC analysis on your model and plot its DC transfer function using the new 'probe_dc' primitive and 'meas_dc' script.

Model of the Month

Successive approximation register (SAR) ADC

Check out how to model a SAR ADC made of a charge-redistribution DAC and successive approximation FSM.
