The circuits presented here use ananalog switch—such as a DG419or one-third of a CD4053—to combinean analog signal with a standard PWMsignal. Most microcontrollers can easilygenerate the PWM signal.

Applications which require the precise monitoring or regulation of dissipated load power, such as motors or servos, can make use of a circuit that measures real power by finding the product of the ...

Current conveyors and capacitance multipliers are fundamental building blocks in modern CMOS technology, facilitating advanced analog signal processing and integrated circuit design. These circuits ...

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 ...
