In 1976, Tsividis demonstrated the first fully integrated MOS (metal oxide semiconductor) operational amplifier, along with its use in a coder-decoder for digital telephony, and proposed detailed design techniques for MOS analog circuits that were widely adopted and led to the first massively produced, mixed-signal integrated circuits.
Areas of Interest: Wireless information networks, cellular networks, packet-switched computer networks, and digital telephony with a focus on the interface between information networking technology, law, and sociology.
A key patent for it was issued in 1920 as it happens, at just the same time that scientists at Bell Labs were first thinking about the theoretical underpinnings of digital telephony, but half a century before there was any commercial value to the concept.
As a result of that effort, according to the authors of a new book, Nokia grabbed the lead over Motorola globally, embracing digital telephony and designing phones that were stylish and easy to use.
Now, a Euro startup called Vox.io plans to challenge them by envisioning how digital telephony should work in 2012 and beyond.

In early Wired, a piece about a five-hundred-thousand-dollar luxury "Superboat" would be followed by a full-page editorial urging readers to contact their legislators to condemn wiretapping (in this case, 1994's Digital Telephony Bill).
The law was passed in 1994 in response to law enforcement's concerns that it was then "going dark" with the advent of digital telephony and the Internet.
