Model of the Month

Modeling a clocked comparator latch with reset, sampling, and regeneration behaviors

Can you model a regenerative amplifier with analog outputs performing reset, sampling, and regeneration? No, a transistor-level model doesn’t count.

Tip of the Month

Digital-to-analog converter (DAC) with finite settling time

Check out how to model a DAC showing a first- or second-order settling response with limits on its slew rate.
