In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits.

It is common for Internet of Things (IoT) devices, industrial sensors, meters, precision, and medical equipment to require both a positive and negative voltage. Often, these voltages must be ...

The LM7705 is a switched capacitor voltage inverter with a low noise, −0.23V fixed negative voltage regulator. This device is designed to be used with low voltage amplifiers to enable the amplifiers ...

The lowest-cost way to achieve this goal is to use a 1-quadrant unipolar dc supply (Fig. 1a) outfitted with a polarity reversal relay. However, using a polarity reversal relay brings with it three ...

Use of buck-boost circuits in switching-regulator ICs. Considerations in level-shift circuit design. Switching regulators with internal level shifting. The magnitude of the negative voltage generated ...

The design of the circuit is aimed to produce a device that would remove microscopic particles from the air instead of using fans and filters, by generating negative ions or ionizing the air. Ion – an ...
