I recently purchased a new oscilloscope for home use. It’s a 250 MHz scope, but I was curious what the actual –3 dB frequency was as most scopes have a bit more upper end margin than their published rating...

This article outlines the current methods used to enable true power-on (TPO) multiturn sensing capabilities and introduces a new simplified solution that is set to reshape both the industrial and automotive position sensing markets...
When a design needs auxiliary voltage rails and the associated current loads are modest, capacitor pump voltage multipliers are often the simplest, cheapest, and most efficient way to make them...
When analog circuits mix with digital, the former are sometimes dissatisfied with the latter’s usual single supply rail. This creates a need for additional, often negative polarity, voltage sources that are commonly provided by capacitive charge pumps...
EPC introduces the 100 V, 1 mOhm EPC2361 GaN FET in compact 3 mm × 5 mm QFN package, offering higher power density for DC-DC conversion...
The logic probe is powered from the device under test – it may be any binary logic, which can be powered in the range +2 V to +6 V...
Differential temperature measurement is a handy way to quantify the performance of heatsinks, thermoelectric coolers, and thermal control in electronic assemblies. Figure illustrates an inexpensive design for a high-resolution differential thermometer utilizing the ∆VBE effect to make accurate measurements with ordinary uncalibrated transistors as precision temperature sensors...
Conventional thermostats are based on separate temperature sensor and heater devices with means for feedback between them. But in some recent EDN design ideas we’ve seen thermostat designs that meld the functions of sensor and heater into a single active device...
Part 3 will explain the hardware conversion of a CNN and specifically the benefits of using an artificial intelligence microcontroller with a hardware-based CNN accelerator...
This is part 2 in a series of articles focusing on the properties and applications of convolutional neural networks, which are mainly used for pattern recognition and the classification of objects...
