Sigma-delta modulation improves resolution in programmable interrupt controller analog outputs

One popular way to reconstruct analog signals in microcontrollers (µCs) is through pulse width modulation (PWM). However, this modulation produces a large number of harmonic components, which limits ...

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 ...
