40 GHz VCO and Frequency Divider in 28 nm FD-SOI CMOS Technology for Automotive Radar Sensors


Abstract: "This paper presents a 40 GHz voltage-controlled oscillator (VCO) and frequency divider chain fabricated in STMicroelectronics 28 nm ultrathin body and box (UTBB) fully depleted silicon-on-insulator (FD-SOI) complementary metal-oxide–semiconductor (CMOS) process with eight metal layers back-end-of-line (BEOL) option. VCOs architecture is based on an LC-tank with p-type metal-oxide�... » read more

Radar Wave Propagation Through Materials


This white paper focuses on electromagnetic (EM) wave propagation through materials. For radar systems, this is of interest when radar must pass through walls, or when designing radomes (cover casings for the radar system). In the process of designing a radome, you should always perform full EM simulation. However, the content of this white paper will help you to first estimate whether a radome... » read more

Packaging Technology Needs Of Automotive Radar Sensors Chips


Automotive radar systems are typically composed of an antenna, front-end radar sensor and back-end signal processor. Current state-of-the-art automotive radar systems make use of the latest integrated circuit and a wide range of packaging technologies. Let’s look a bit further into the development of automotive radar sensor chips and the packaging technologies being used as solutions for this... » read more

Sensor Fusion Everywhere


How do you distinguish between background noise and the sound of an intruder breaking glass? David Jones, head of marketing and business development for intuitive sensing solutions at Infineon, looks at what types of sensors are being developed, what happens when different sensors are combined, what those sensors are being used for today, and what they will be used for in the future. » read more

Customizing Chips For Power And Performance


Sandro Cerato, senior vice president and CTO of the Power & Sensor Systems Business Unit at Infineon Technologies, sat down with Semiconductor Engineering to talk about fundamental shifts in chip design with the rollout of the edge, AI, and more customized solutions. What follows are excerpts of that conversation. SE: The chip market is starting to fall into three distinct buckets, the e... » read more

Making Lidar More Useful


Lidar, one of a trio of “vision” technologies slated for cars of the future, is improving both in terms of form and function. Willard Tu, director of automotive at Xilinx, talks with Semiconductor Engineering about different approaches and tradeoffs between cost, compute intensity and resolution, various range and field of view options, and why convolutional neural networks are so important... » read more

Shifting Auto Architectures


Domain controllers and gateways are being replaced by central processing modules and zonal gateways to handle all of the data traffic in a vehicle. Ron DiGiuseppe, automotive IP segment manager at Synopsys, talks with Semiconductor Engineering about how automotive applications are changing, what that means for engineering teams, and how they will shift as AI is increasingly deployed. » read more

Overcoming Next-Generation AESA Radar Design Challenges


Phased array antennas were first used in military radar systems to scan the radar beam quickly across the sky to detect planes and missiles. These systems are becoming popular for a variety of applications and new active electronically scanned arrays (AESAs) are being used for radar systems in satellites and unmanned aerial vehicles. As these systems are deployed in new and novel ways, size and... » read more

A Look Inside ADAS Modules


You glance down at your phone while rolling in slow-moving traffic. Against your better judgment, you proceed to read your latest email, oblivious to the fact that the car in front of you has braked. In the nick of time, your car starts beeping and flashing. You look up and slam the brakes. Whew! That was close. If this has happened to you, don't forget to thank the radar and camera modules in ... » read more

Manufacturing Bits: Nov. 25


Lidar-on-a-chip At the upcoming IEEE International Electron Devices Meeting (IEDM), Samsung will present a paper on the industry’s first single-chip lidar beam scanner. (Go to this link and then look for paper 7.2, “Single-Chip Beam Scanner with Integrated Light Source for Real-Time Light Detection and Ranging,” J. Lee et al, Samsung.) Lidar, or light imaging, detection, and ranging, ... » read more
