    • Noise-reducing transistor arrangement having first and second field effect transistors (FETs) having source terminals coupled together, drain terminals coupled together, and control terminals for application of a first or second signal. A clock generator unit is configured to provide the first and second signals alternately to the FETs with an alternating frequency which is at least as great as the cut-off frequency of the noise characteristic of the FETs, or with a reciprocal alternating frequency which is less than a mean lifetime of an occupation state of a defect in the boundary region between channel region and gate insulating layer of the FETs. The first signal is applied to the control terminal of the first FET and, simultaneously, the second signal to the control terminal of the second FET. The second signal is applied to the control terminal of the first FET and, simultaneously, the first signal to the control terminal of the second FET.
    • 具有第一和第二场效应晶体管(FET)的降噪晶体管装置,其具有耦合在一起的源极端子,耦合在一起的漏极端子和用于施加第一或第二信号的控制端子。 时钟发生器单元被配置为以至少与FET的噪声特性的截止频率一样大的交变频率或者具有较小的互逆交变频率来向FET施加交替的第一和第二信号 比FET的沟道区域和栅极绝缘层之间的边界区域的缺陷的占用状态的平均寿命长。 第一信号被施加到第一FET的控制端子,并且同时将第二信号施加到第二FET的控制端子。 第二信号被施加到第一FET的控制端,同时将第一信号施加到第二FET的控制端。
