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.

Before I start messing with the B21 trick I would like to know some details on the circuit - what does it take to build it, what does it cost, can I buy it somewhere, etc.?<BR><BR>The dual Celeron ...

It is an age-old problem. You have a 2.5 GHz source and you want it at 5 GHz. You need a frequency doubler. [All Electronics Channel] has an interesting video that talks not only about the theory of ...

Fig 1. Two analog multipliers form a VCO with quadrature outputs, while a third multiplier provides AGC to stabilize output voltages without adding distortion. Fig 2. The oscilloscope trace of the VCO ...
