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.

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 ...

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.

Remember learning all about functions in algebra? Neither do we. Oh sure, most of us remember linear plots and the magic of understanding y=mx+b for the first time. But a lot of us managed to slide by ...

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

The cult of DSPism believes that eventually there will be essentially no analog circuits, that all circuitry will be either digital, as microcontrollers (μCs), with mixed-technology ADCs and DACs.
