  • Abstract
    The potential performances and limitations of an all-analogue implementation of a posteriori-probability (APP) decoders in a standard complementary-metal-oxide semiconductor (CMOS) technology are investigated. In particular, the accuracy and speed trade-off related to the usage of MOS transistors in the weak inversion (w.i) region is analysed in depth. Transistor level simulations of a (18, 9, 5) tail-biting decoder are reported and contrasted with the results of the software implementation of the same decoding algorithm
