analog with a hint of digital. For receivers, we have adaptive feedback - feedback gain varying via pulse signals as function of process variation.
But, as fas as PAs are concerned : except for enveope tracking, it's going to be analog unless we have PAs integrated into ASICs (or when GaAs can be cost effectively integrated with silicon).
People ate trying, but we are in a transition. There is no way you can have digital LNA or digital PA. Impossible. Although circuits controlling LNAs, PAs and mixers are digital - something like adaptive biasing or variable load pull digitally via switched capacitors.
hm, agree with you that the distant relative will eventually be acknowledge and use in more areas that already are. However, these distant relatives STILL NEED TO INTERACT WITH their Analog counterparts to do any common-good. ;-)
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.
