Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a capacitance that can be varied by changing the applied voltage. These types of diodes often are used for ...

This year’s top Idea for Design, “Use A DAC To Bias Your Varactor Diode” by Jefferay Lawton, calls to mind an injunction ascribed to Albert Einstein to “make things as simple as possible, but no ...

Multiplexing is a very old technology in which control signals are intermixed for the sake of being able to control more devices than there are control signals. For [mihai.cuciuc], the problems ...
