Problem

Problem

This digital communications company worked for 2 years on the design for this 80 MSPS analog-to-digital converter (ADC), but it did not meet specs. The device was poorly laid out with bad device matching. Noise kept this ADC at only 8 bit accuracy.

Solution

Solution

iSine engineers improved the matching, reduced cross-talk, improved the device sizing, and added substrate isolation. iSine accomplished this in 4 months compared to the 48 months that the customer had been working on the chip.

Results

Results

The ADC achieved 13 bit accuracy in an 80 MSPS design.
