Noise Properties of a Resonance-Type Spin-Torque Microwave Detector (PREPRINT)

Abstract

We analyze performance of a resonance-type spin-torque microwave detector (STMD) in the presence of noise and reveal two distinct regimes of STMD operation. In the first (high-frequency) regime the minimum detectable microwave power P(min) is limited by the low-frequency Johnson-Nyquist noise and the signal-to-noise ratio (SNR) of STMD is proportional to the input microwave power PRF. In the second (low-frequency) regime P(min) is limited by the magnetic noise, and the SNR is proportional to the square root of P(RF). The developed formalism can be used for the optimization of the practical noise-handling parameters of a STMD.
