Abstract
We have developed a 2-bit 32 GS/s soft decision LSI in 0.13 μm SiGe-BiCMOS. The LSI includes a flash type Analogue-to-Digital converter and an encoder which outputs the soft decision results, which are a hard decision bit and a confidence bit for strong Forward Error Correction. We have confirmed that the LSI has 25 mVpp sensitivity and the LSI enables 2 dB better FEC coding gain than hard decision.
