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.

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 ...

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.

Current mode analog multipliers and dividers represent a pivotal advancement in the realm of mixed-signal processing and integrated circuit design. These devices utilise current signals for ...

When I worked at Analog Devices, every new engineer received a package of materials on his first day of work. The package included several books edited by ADI's Dan Sheingold — the Data Conversion ...
