Resilience is Key to the Connected and Autonomous Revolution
INTRODUCTION Connected and autonomous vehicles have long been hailed as the answer to safe transport. Around 1.25 million people die in road traffic accidents worldwide each year according to E&T– and driver error accounts for over 90 per cent of those deaths[1]. In theory, the removal of the driver as the lead decision maker for vehicle control should reduce this number, … [Read more...]

Choosing and Using Silicon Protection Devices
Introduction Correctly choosing an external (off chip) Transient Voltage Suppressor (TVS) is not as simple as it once was. Integrated Circuit (IC) feature size is shrinking (Figure 1) and more and more inputs are being exposed to the outside world. Portable consumer devices are everywhere and have more functions in smaller and smaller sizes, necessitating smaller and smaller … [Read more...]
