It is called ambipolar because it changes its behavior. It acts like a p-channel FET when the gate is at one polarity and an n-channel FET when the gate is at the other. So, it wanders ("ambi", think "amble" or like "ambidextrous") between polarities. What I am curious about is whether there is a dead band between polarities and is that controllable. I would also like to see a couple of simplified schematics using the device.
Life could become really interesting; does ambipolar therefore not need a substrate bias to prevent latchup? Could we discard our old 'nominal 0V' substrate and run everything in true differential? Every signal could have a mirror in the opposite polarity, giving potential for low crosstalk and low supply voltages/signal swings... could also make it easier to recycle charge locally instead of burning it in resistive losses.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
