Abstract
Low frequency noise properties of all-thin film superconductor-constri ctions-superconductor devices have been investigated. We first found t hat the magnitude of 1/f noise level rapidly decreases with increasing the device quality factor Q(-1) and saturates for Q(-1)greater than o r equal to 2. From Hooge theory [1] this saturation phenomena indicate s that the number of carriers in the system no longer changes for Q(-1 )greater than or equal to 2.
