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

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.
