What Is Machine Learning? Part 3 - Hardware Conversion of Convolutional Neural Networks
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...
What is machine learning? Part 2 - Training convolutional neural networks
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...
What is machine learning? Part 1 - Introduction to convolutional neural networks
The world of artificial intelligence (AI) is rapidly evolving, and AI is increasingly enabling applications that were previously unattainable or very difficult to implement. This series of articles explains convolutional neural networks and their significance in machine learning within AI systems...
Lowering quiescent current by a factor of 4 in an electronic latching switch
The circuit shows an electronic switch driven by a momentary pushbutton, which turns the power alternately on and off. It was designed for battery-powered equipment...
Fast-settling picoammeter circuit handles wide voltage range
Evaluating analog switches, multiplexers, operational amplifiers, and other ICs poses challenges to IC-test engineers. A typical test scenario requires application of a test or forcing voltage to a device's input and measurement of any resultant leakage and offset currents...
Transistors offer thermal protection for controller
When a switch-mode power-supply controller, such as NCP1200, operates at a high ambient temperature, you should protect the entire power supply against lethal thermal runaway...
Bipolars provide safe latch-off against opto failures
A typical SMPS uses a reference voltage and an optocoupler to regulate the output voltage. The optocoupler carries the isolated information from the secondary side to the primary nonisolated side and ensures proper output regulation...
Switching regulator provides ±15 V output from an 8 V to 40 V input without a transformer
Many systems derive ±15 V supplies for analog circuitry from an input voltage that may be above or below the 15 V output...
Vishay Intertechnology's new proximity sensor offers idle current down to 5 μA in compact 2.0 mm x 1.0 mm x 0.5 mm SMD package
The Optoelectronics group of Vishay Intertechnology introduced a new fully integrated proximity sensor designed to increase efficiency and performance in consumer applications...
