Sammanfattning

Measurement results of an analog channel decoder in 65 nm CMOS are presented. We target ultra compact and low power applications with low to medium throughput requirements. The decoding core is designed for (7,5)(8) convolutional codes and takes 0.104 mm(2) on silicon. The degrading effects of analog imperfections are investigated and the presented results allow power, performance and throughput trade-offs. Analyzing the bit error rate (BER) performance under extreme power constraints provides insights on energy efficiency and limitations of small scale analog decoders. For the limited power budget of 3 W the decoder performs the required computations to provide 1 dB of coding gain at BER=0.001 for 500 kb/s throughput. The presented chip has digital I/O that facilitates embedding it in a conventional digital receiver.
