Low-Noise Parametric Resonant Amplifier [PDF]
IEEE Transactions on Circuits and Systems I: Regular Papers, 2011 We propose a resonant parametric amplifier with an enhanced noise performance by exploiting the noise-squeezing effect. Noise squeezing occurs through the phase-sensitive amplification process and suppresses one of the two quadrature components of the input noise. When the input signal is only in the direction of the nonsuppressed quadrature component,
