MIPI Deployment In Ultra-Low-Power Streaming Sensors


Streams of data from higher-speed sensors pose throughput and latency challenges for designers. However, optimizing a design for those criteria can come at the expense of increased power consumption if not conceived and executed carefully. A device like a high-resolution, high-frame-rate home security camera in a non-wired application requiring frequent battery changes or recharging will likely... » read more

Dealing With Noise In Image Sensors


The expanding use and importance of image sensors in safety-critical applications such as automotive and medical devices has transformed noise from an annoyance into a life-threatening problem that requires a real-time solution. In consumer cameras, noise typically results in grainy images, often associated with poor lighting, the speed at which an image is captured, or a faulty sensor. Typi... » read more

A New Approach For Sensor Design


Pawel Malinowski, program manager at imec, sat down with Semiconductor Engineering to discuss what's changing in sensor technology and why. What follows are excerpts of that discussion. SE: What's next for sensor technology? Malinowski: We are trying to find a new way of making image sensors because we want to get out of the limitations of silicon photodiodes. Silicon is a perfect materi... » 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

Image Sensors Are Everywhere And The Implications For Test Are Significant


In February of 2021, the NASA Perseverance rover actively navigated a fully-autonomous entry and descent to successfully land in the Jezero Crater on Mars, using a brand-new navigational system developed by NASA – Terrain-Relative Navigation. The delay between mission control and the rover was about 11 minutes so a human-guided remote landing was not possible. Previous missions had to rely o... » read more

Novel In-Pixel-in-Memory (P2M) Paradigm for Edge Intelligence (USC)


A new technical paper titled "A processing-in-pixel-in-memory paradigm for resource-constrained TinyML applications" was published by researchers at University of Southern California (USC). According to the paper, "we propose a novel Processing-in-Pixel-in-memory (P2M) paradigm, that customizes the pixel array by adding support for analog multi-channel, multi-bit convolution, batch normaliza... » read more

MIT: Stackable AI Chip With Lego-style Design


New technical paper titled "Reconfigurable heterogeneous integration using stackable chips with embedded artificial intelligence" from researchers at MIT, along with Harvard University, Tsinghua University, Zhejiang University, and others. Partial Abstract: "Here we report stackable hetero-integrated chips that use optoelectronic device arrays for chip-to-chip communication and neuromorphic... » read more

Audio, Visual Advances Intensify IC Design Tradeoffs


A spike in the number of audio and visual sensors is greatly increasing design complexity in chips and systems, forcing engineers to make tradeoffs that can affect performance, power, and cost. Collectively, these sensors generate so much data that designers must consider where to process different data, how to prioritize it, and how to optimize it for specific applications. The tradeoffs in... » read more

Detecting Spatial Blotches In Image Sensor Devices


One of the most common defects in image sensor devices is spatial blotches. The appearance of blotches in image sensors is a regular occurrence and may be generated by internal moving parts or may be moved by air currents within the camera. Composed of two main statistical methods, the first module employs an inferential method, applying a spatial segmentation of the current frame to obtain ... » read more
