supporting wireless applications such as real
time data synchronization between mobile
devices and dock stations, full-HD video
streaming between mobile electronics and
HD-TVs or HD-projectors, and high speed
wireless links from terminals to wireless
AP etc. The communication data rate for
the aforementioned applications could reach
up to several giga-bit-per-second (Gbps).
IEEE standards 802.11ac and 802.11ad
have been released this year aiming at next
generation Wi-Fi [1]. The 802.11ac standard
is a evolution of 802.11a/b/g/n, which
incorporates techniques such as 80MHz wide
bandwidth, high order modulation schemes
up to 256QAM, and multi-input multi-output
(MIMO), and the physical data rate could
reach to >1Gbps. On the other hand, the
802.11ad standard reserves the conventional
Wi-Fi paradigms around 2.4GHz and 5GHz
bands, while adopts the millimeter wave
(mmW) band communication standard around
60GHz with 7GHz unlicensed ultra-wide
band and four 2.16GHz consecutive channels,
supporting 16QAM modulation schemes and
beamforming. The physical data rate could be
boosted to 7Gbps. Millimeter wave wireless
communication around 60GHz therefore be-
comes increasingly attractive and promising
for the next generation Wi-Fi with multi-Gbps
data throughput.
Wireless transceivers working on the 7GHz
Abstract: In this paper, a fully integrated
CMOS receiver frontend for high-speed
short range wireless applications centering
at 60GHz millimeter wave (mmW) band is
designed and implemented in 90nm CMOS
technology. The 60GHz receiver is designed
based on the super-heterodyne architecture
consisting of a low noise amplifier (LNA)
with inter-stage peaking technique, a single-
balanced RF mixer, an IF amplifier, and a
double-balanced I/Q down-conversion IF
mixer. The proposed 60GHz receiver frontend
derives from the sliding-IF structure and is
designed with 7GHz ultra-wide bandwidth
around 60GHz, supporting four 2.16GHz
receiving channels from IEEE 802.11ad
standard for next generation high speed Wi-
Fi applications. Measured results show that
the entire receiver achieves a peak gain of
12dB and an input 1-dB compression point of
-14.5dBm, with a noise figure of lower than
7dB, while consumes a total DC current of
only 60mA from a 1.2V voltage supply.
