A 7-bit 18th order 9.6 GS/s FIR filter for high data rate 60-GHz wireless communications

This paper presents the design and measurements of a 4× oversampled 18th order digital low-pass FIR filter aimed at replacing all analog baseband filters in a 60 GHz high data-rate wireless communication transmitter. Pipeline CPL adders and TSPC flip-flops are used to enable a very high output sampl...

Zusammenfassung:This paper presents the design and measurements of a 4× oversampled 18th order digital low-pass FIR filter aimed at replacing all analog baseband filters in a 60 GHz high data-rate wireless communication transmitter. Pipeline CPL adders and TSPC flip-flops are used to enable a very high output sample rate. The filter area is 0.1mm 2 in a standard 65nm CMOS process. The interpolator has been designed to work at 10 GS/s. Measurements can be performed up-to 9.6 GHz on a 1.4V supply voltage and the filter consumes 400 mW.
