Abstract
This paper describes a low-power-consumption di-
rect-conversion CMOS transceiver for WLAN systems operating
at 4.9–5.95 GHz. Its power consumption is reduced by using
a resonator-switching wide-dynamic-range LNA. The broad
tuning range needed for multiple-channel-bandwidth systems
is provided by a single widely tunable low-pass filter based on
negative-source-degeneration-resistor transconductors, and its
automatic frequency-band-selection PLL supports multiple stan-
dard 5-GHz WLAN systems. The
