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.

It is sometimes necessary for a microcontroller to generate a pulse whose voltage is higher than the power-supply voltage of the microcontroller. The circuit in Figure 1 allows you to generate 14V ...

Researchers from Ulsan National Institute of Science and Technology (UNIST) designed a low power semiconductor circuit ...

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.

With the increase in fabrication density over the last few decades, semiconductor technology is being pushed to extreme limits and power dissipation has become a major issue. Researchers have been ...

Everyone loves to play with electricity and plasma, and [Hyperspace Pirate] is no exception. Inspired by a couple of 40×20 N52 neodymium magnets he had kicking around, he decided to put together a ...
