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 ...

This circuit design for a current-mode analog multiplier/ divider is based on current-controlled conveyors (CCCII) and a second-generation current conveyor (CCII). No passive components are used.

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