Circuit Designers: An Endangered Species?

Overview of the impact of sophisticated CAD software on today's analog design engineer
November 1, 2001
Special Report Circuit Designers: An Endangered Species? Ernest Rejman, Contributing Editor Back in the Jurassic Period, when the four-function calculator first made its appearance, some greeted it with dismay. "Suitable for imbeciles," spat an elder engineer of my acquaintance. "Now it won't be necessary to even know how to...
