Research Bits: Mar. 9


Low noise clock generator Researchers from Ulsan National Institute of Science and Technology (UNIST) designed a low power semiconductor circuit capable of generating high-quality clock signals with significantly reduced noise levels. The injection-locked clock multiplier (ILCM) circuit uses a simplified design based on a ring voltage-controlled oscillator (VCO). It integrates a frequency t... » read more

How Many Sensors For Autonomous Driving?


With the cost of sensors ranging from $15 to $1,000, carmakers are beginning to question how many sensors are needed for vehicles to be fully autonomous at least part of the time. Those sensors are used to collect data about the surrounding environment, and they include image, lidar, radar, ultrasonic, and thermal sensors. One type of sensor is not sufficient, because each has its limitation... » read more
