Abstract: The analog baseband section of a receiver for
high data-rate 60GHz wireless communications is
implemented in 90nm CMOS. It consists of the cascade of a
1st-order transimpedance amplifier with finely
programmable gain, a 4th-order source-follower based filter
and a coarse gain 1st-order programmable gain amplifier,
resulting in an overall 6th-order selectivity and a 1GHz cutoff
frequency. Gain can be programmed from 0dB up to
20dB with 1dB step control, drawing 9.5mA (0NjdB gain
range) or 10.8mA (10ᆨdB gain range) from a 1V supply. A
8.2dBm IIP3 and a 끙dBm/Hz IRN are measured
respectively at 0dB and 20dB gain. The entire baseband
section occupies 400x390 square mm die area.
