SESSION 12
8:30 AM
A low-noise active balun achieves broadband impedance matching, low noise and high IIP2 at
the same time by introducing a low-noise IM2-cancellation feedback. The measured minimum
IIP2 is 28dBm, showing an improvement of 9dB. The circuit achieves IIP3 of 2.5dBm and NF of
3.5 to 4.5dB, while consuming 7.8mW from a 1.2V supply.

A differential common-gate 0.18μm CMOS LNA is designed with both positive and negative
feedback to boost gain, partially cancel noise, and consume low power without sacrificing the
bandwidth and linearity advantages of a CG topology. The measurement results show 21dB
voltage gain, 2dB minimum NF, and -3.2dB IIP3 while drawing 2mA from a 1.8V supply.
12.3 A Compact Low-Noise Weighted Distributed Amplifier in CMOS

The finite impulse response of a weighted distributed amplifier is used to selectively suppress
noise at predetermined frequencies and integrate ESD protection. A 0.13μm CMOS
1-to-10.6GHz LNA with a minimum NF of 2.5dB and a power gain of 11 to 13dB, consuming
17mW of power and occupying 0.43mm2 is demonstrated.
12.4 A 0.2-to-2.0GHz 65nm CMOS Receiver Without LNA Achieving >11dBm IIP3 and
19dB, IIP3>11dBm and NF
