Take a risk; throw away those bits! 10/22/2009

You can create a 12-bit system using a 24-bit converter and eliminate the need for analog gain and level-shifting circuits.

Real signals 10/8/2009

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 9/17/2009

When selecting the proper operational amplifier for your circuit, you need to know how much gain error your design can tolerate.

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 8/20/2009

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?

The nature of ESD 8/6/2009

To control ESD (electrostatic-discharge) transient currents, you must design the system so that ESD events have only one clear path to ground at every single point.
