In this paper, a phase noise cancellation (PNC) architecture is presented for 60 GHz communication systems. The BER performance is severely degraded by the non-ideal carrier frequency in 60 GHz bandwidth, which causes both common phase error (CPE) and residual carrier frequency offset (RCFO). The proposed simplified two-stage CPE algorithm solves the RCFO and common phase nose in the frequency domain and eliminates the constellation rotation on each sub-channel. Two-stage architecture together with deep pipelining technique achieves a high throughput rate. This PNC architecture has been implemented in a SC/OFDM Dual-Mode baseband receiver satisfying the requirements of the 802.15.3c/802.11ad standard with a 40 nm process. The proposed PNC is able to support 64QAM/16QAM for OFDM/SC mode, and can achieve up to 19.2 Giga-bit per second (Gbps) throughput rate at 400 MHz operating frequency with power consumption of 33 mW and area of 0.142 mm2.
