N2 - A LNA using noise squeezing is designed in a 65 nm CMOS. The noise squeezing occurs through phase sensitive gain implemented by parametric process. This process is carried out inside a nonlinear resonator where energy transfers from a pump to the signal. When the pump frequency is twice that of the signal, the amplifier suppresses one of two quadrature components of the input noise. This concept is exploited to realize an 8 GHz LNA with 0.45 dB NF for non-suppressed quadrature.
