Hello Vivek : For decimation filtering for delta-sigma ADCs, R. Jacob Baker's <<CMOS: Mixed-Signal Circuit Design, Second Edition>> is a good book. Many DSP book also have the theory of Sinc and halfband filter. For low power consumption: 1: choose the right order of filter and coefficient. 2: the logic architecture of filter: topology of pipeline(dff vs latch), how many adders and multipliers and their bits needed. 3: arithmetic operation block logic design choice: adder: carry ripple/select/look-ahead ... adder? multiplier: csa tree , wallace tree, booth encoder, fused multiply-Add......? 4: transistor circuit map: combinational circuit: CMOS logic, CPL, CVSL, clock and power gating.... DFF/Latch: Maste-slave dff, pulse latch, TSPC, Strong-ARM DFF,Semidynamic DFF, logic fused dff/latch.... A very good book for circuit and logic design, Neil H. E. Weste, D. Harris, CMOS VLSI Design: A Circuits and Systems Perspective, 3th Edition, Pearson Education Press. Hope helpful!
********************************************************** Hi,
I have never designed digital filters so far (although I did study a bit of DSP at school). I was looking for a good reference that gives the necessary basics to design practical, power-efficient digital filters. Would anyone be able to recommend some papers? I already have the regular DSP books, but they are not very useful in these things.
Hint: The main application would be decimation filtering for delta-sigma ADCs, and power consumption is naturally critical.
Thanks, Vivek
