Old-School Analog Temperature Control Circuits Solved with Modern LT spice Thermistor Dynamic Models, Part 2

This temperature profile is one of the principal reasons why we need a PID controller, which will be able to very accurately follow the required dwells and slopes, while also avoiding big oscillations ...

Analog circuits need more than just DFT methods

Digital design is, of necessity, performed at a very high level of abstraction. When dealing with millions to hundreds of millions of transistors, working at the transistor level is completely ...

Even in a Digital World, Analog Multipliers are Still Relevant

In a digital world, why bother with analog? Well, sometimes it can still be the right solution. Take, for instance, the analog multiplier (see figure). At its simplest, it’s a circuit that leverages ...
