Figure B.2.2.1. Block diagram <strong>for</strong> an analog implementation <strong>of</strong> a CS channel <strong>for</strong> neuralacquisition.The total power cost <strong>for</strong> the analog implementation <strong>of</strong> a multipath CS encoder, without tak<strong>in</strong>g<strong>in</strong>to consideration the random generation and the mixers cost, has been calculated <strong>in</strong> [3] as:(25)Figure B.2.2.2. Power consumption versus bandwidth <strong>for</strong> the analog implementation <strong>of</strong> a CSpath. Specifications from Table 3.1.1 have been taken <strong>in</strong>to consideration.Tthe power consumption has been <strong>in</strong>troduced versus the bandwidth <strong>of</strong> the <strong>in</strong>put signal, (seeFig. B.2.2.2). In this case, regard<strong>in</strong>g to the calculations have been presented above, the largestcontribution to the power consumption is the one due to each <strong>of</strong> the amplifiers which have beenconsidered as necessary <strong>for</strong> each <strong>of</strong> the paths <strong>of</strong> the matrix multiplication.
