Abstract
This paper discusses design and measurements of

a flexible Viterbi decoder fabricated in 130-nm digital CMOS.

Flexibility was incorporated by providing various code rates and

modulation schemes to adjust to varying channel conditions.

Based on previous trade-off studies, flexible building blocks were

carefully designed to cause as little area penalty as possible. The

chip runs down to a minimal core supply of 0.8V. It turns out that

striving for more modulation schemes is beneficial in terms of

power consumption once the price is paid for accepting different

code rates viz. radices in the trellis and survivor path units.
