Boeing postpones test flights again: How’s your tapeout looking?
Boeing's recent issues offer a cautionary tale for any chip-design team engaged in a complex project.
Shaping edges
There are many ways to make properly shaped signal edges, but they are each equivalent to some linear filtering operation.
Take a risk; throw away those bits!
You can create a 12-bit system using a 24-bit converter and eliminate the need for analog gain and level-shifting circuits.
Exhibits emphasize markets and development ease
Vendors at the Embedded Systems Conference in Boston September 21 and 22 highlighted an impressive range of technologies that address issues ranging from "green" applications to data and code security.
Real signals
The piecewise-linear step starts with a jerk, mindlessly follows a perfectly uniform ramp, and smacks hard into its upper limit. Real signals don't do that.
A designer's guide to op-amp gain error
When selecting the proper operational amplifier for your circuit, you need to know how much gain error your design can tolerate.
Robots, jobs, and war
Many ethical questions are being raised as robots take on more and more roles in society.
In a downturn, treat your customers right
There is no need to worry about the economic downturn if you realize businesses are here for the customers, not the other way around.
Sliding edge
Boards with different transmission-line geometries require special techniques. Here's how to cope when high-speed signals reflect due to the sudden change in board properties as they move across the connection.
One circuit provides system resolution and 12-bit accuracy
Handheld meters, data loggers, and automotive and monitoring systems typically require a multiplexed system with good accuracy and high system resolution. Is it possible to get this mixture of requirements into one circuit?
