Many older linear devices, especially operational amplifiers (op amps) do not have a SPICE macro model. Even when they do, older models typically use a Boyle macro model which, by today’s standards, ...
Many designers have asked why CPF has the macro model commands while UPF/1801 does not. I will try to answer this question and explain the differences in both approaches. First, let’s briefly review ...
In part 1 of this three-part article, I provided the necessary equations to develop your own macro model for a bipolar-input operational amplifier (op amp). In part 2, we will look at a different ...
