Making Too Much Noise


By Ed Sperling For the better part of a decade talk about signal integrity in mixed-signal designs has been noticeably absent. That’s about to change. Prior to the adoption of a 130nm process, many semiconductor companies actually went on record saying they were considering abandoning plans to ever put analog and digital on the same chip because the noise on digital would interrupt signal... » read more

Low-Power And RF Design Heighten Signal-Integrity Concerns


By Ellen Konieczny As active devices and interconnect wires shrink and are placed closer together with the march of Moore’s Law, signal integrity is becoming a huge concern. If it is not maintained, a design’s future may be marred by lower yields, unreliable performance, and failure to work efficiently—if at all. For low-power and radio-frequency (RF) designs, which are being prod... » read more
