Hi Rajasekhar and SBR,
thanks for sharing.
For the equation derived in the appendix it has two problems. In passive filters we don't really talk about power dissipation, although the equation may be correct. For active filters, orders of magnitude doesn't begin to decribe how far off the equation could be. For example A.19,
Pi = 8kTf
0S/N
Let S/N = 10 and f0 = 1 MHz. Then Pi = 3.2016*10^-13 W. I haven't heard of an active filter operating with less than the order of microwatts. The problem comes from the authors use of an output swing of Vdd which almost never happens in active filters.
BTW the author mentions
Quote:The dynamic range specified is the range of input signals over which THD ≥ 40 dB and S/N > 0 dB are maintained.
So DR is basically a ratio of two signal strengths while SNR is the ratio of signal to noise strength. In my opinion it makes sense that if you want an overall SNR of 20 dB, then the maximum signal strength gives THD of 20 dB and minimum gives SNR (where N is random noise) of 20 dB.
Anyway overall the thesis looks quite interesting so thanks for sharing. I will have a look.
cheers,
Aaron
