BLDC Motors Put the Power in Present Day Power Tools

Jose Quinones, Senior Applications Engineer, Programmable Power Management, Qorvo

The first idea that electricity could be used to produce rotary motion originates in the 1740s in experiments by a Scottish Benedictine monk, Andrew Gordon. It took nearly another century before a practical battery-operated version appeared in 1834 and then, through the work of Tesla and others, the ground wa

How to Cancel Ambient Light for LIDAR Receivers

Noe Quintero, Analog Design Engineer, Analog Devices

LIDAR works by using a laser to send out a narrow pulse of light, which hits a target, and the light reflects back. A detector measures the time the reflection takes to return. By knowing the speed of light and round trip time of the laser pulse, the distance can be calculated. Generally, the higher the amplitude of
