In the proximity detector, a 4-in.-sq piece of copper-plated pc board serves as an antenna that forms one plate of a capacitor...
Lighting LEDs from a single 1.5 V cell poses a problem because their forward voltages are higher than the cell’s. The simplest way to light the LED is to use a step-up dc/dc converter. This Design Idea offers a simple and reliable alternative...
Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, and the inverter input current...
Many electronic-control systems have digital outputs that use transistors. One method of improving the security in these outputs is to use an oscillating signal to represent a logic-high state instead of a fixed voltage level...
This precision thermocouple sensor module performs cold-junction compensation and digitizes the signal from any type of thermocouple. The output data is formatted in degrees Celsius...
Readers will recognize the famous name Claude Elwood Shannon, widely renowned as the “father of information theory” and originator of many discoveries and inventions. Among these is an elegant and pioneering design idea for a DAC called the Shannon Decoder...
The standard boost converter uses not only IC1, C1, L 1, D1, and C2 to generate a main 5 V output, but also additional small, low-cost components to provide two auxiliary supply rails of 10 and –5 V...
It is sometimes necessary for a microcontroller to generate a pulse whose voltage is higher than the power-supply voltage of the microcontroller...
EPC introduces the 150 V, 3 mΩ EPC2305 and the 200 V, 5 mΩ EPC2304 GaN FETs in a thermally enhanced QFN package with exposed top and tiny 3 mm × 5 mm footprint...
