Abstract :
This paper presents the design and measurement of a 4 × oversampled 18th order digital low-pass FIR filter. It is a key building block in the proposed digitally enhanced transmitter architecture for 60 GHz wireless high-data rate links. Spectrum mask requirements are fully satisfied for OFDM modulated signals without requiring additional analog filtering. Pipelined CPL adders and TSPC flip-flops are used to enable a very high operation frequency. The core area is 0.1 mm2 in a standard GP 65 nm CMOS process. Measured power consumption is 400 mW at 9.6 GS/s with a 1.4 V power supply voltage.
