This paper presents low-power, small area analog baseband (ABB) circuits for 60 GHz wireless transceiver in 40 nm CMOS. The ABB circuits consist of 0-to-40 dB VGAs and 5-bit 2304 MS/s flash ADCs for the receiver, and 6-bit 3456 MS/s DACs for the transmitter. The VGAs also work as 2-2-1 order low-pass filters by using negative capacitance generator. The receiver demonstrates SNDR of 27.3 dB at 2304 MS/s with 16 dB VGA gain. The DAC demonstrates SFDR of 40 dB at 3456 MS/s up to 200 MHz. VGAs, ADCs and DACs consume 18 mW, 24 mW and 42 mW from a 1.1 V supply, respectively. The entire ABB circuits occupy an area of 0.36 mm2.
