FIR filter for high speed 60 GHz wireless communications.

Abstract

In this thesis report the design and implementation of the FIR filter at 5 GS/s presented. IEEE 802.15.3c standard declared unlicensed band from 57 to 66 GHz. This 60 GHz wireless communication transmitter uses interpolator filter part of this works at 5 GS/s. In this report 6 order 5 GS/s FIR filter implementation is described. In 180nm technology speed requirement cannot be achieved. Using the 45 nm technology this FIR filter is implemented and tested. The FIR filter structure is designed in bit pipelined structure. The key part are CPL adder and TSPC Flip-Flop. These adder and FF enabled very high frequency operation at 7.35 GHz. This led to implementation of 5 GS/s FIR filter using power of 2 coefficients.
