A 1.2 V and 69 mW 60 GHz Multi-channel Tunable CMOS Receiver Design

A multi-channel receiver operating between 56 GHz and 70 GHz for coverage of different 60 GHz bands worldwide is implemented with a 90 nm Complementary Metal-Oxide Semiconductor (CMOS) process. The receiver containing an LNA, a frequency down-conversion mixer and a variable gain amplifier incorporating a bandpass filter is designed and implemented. This integrated receiver is tested at four channels of center frequencies 58.3 GHz, 60.5 GHz, 62.6 GHz and 64.8 GHz, employing a frequency plan of an 8 GHz-intermediate frequency (IF). The achieved conversion gain by coarse gain control is between 4.8 dB and 54.9 dB. The millimeter-wave receiver circuit is biased with a 1.2 V supply voltage. The measured power consumption is 69 mW.
