    • A sense amplifier includes at least two field effect transistors of identical conductivity type, each including a gate terminal, a source terminal, a drain terminal and a bulk terminal. The two field effect transistors are connected such that they are coupled back-to-back between a bit line and a reference line. The bit line is connected to a memory node via a selection transistor. The field effect transistors include bulk or substrate terminals formed in mutually insulated, different wells. The substrate bias voltages and thus the threshold voltages can be set independently via the body effect, so that the threshold voltages that are fundamentally different on account of stochastic effects in the different wells can be adapted to one another. Thus, compensating for the disadvantages that occur in conventional wells, on account of scattering effects during implantation or on account of mechanical stresses which act differently on transistors that are otherwise formed uniformly in the same well.
    • 读出放大器包括至少两个具有相同导电类型的场效应晶体管,每个场效应晶体管均包括栅极端子,源极端子,漏极端子和体积端子。 两个场效应晶体管被连接,使得它们在位线和参考线之间背靠背耦合。 位线通过选择晶体管连接到存储器节点。 场效应晶体管包括形成在相互绝缘的不同阱中的体积或衬底端子。 衬底偏置电压以及因此阈值电压可以经由身体效应独立地设定,使得由于不同井中随机效应而根本不同的阈值电压可以彼此适应。 因此,补偿在常规孔中出现的缺点,由于植入过程中的散射效应,或由于另外在同一孔中均匀地形成的晶体管上作用不同的机械应力。

    • A releasable and stress-free securing assembly for an optical element (2, 3) positioned in a centered manner in a mount (1) is provided. The optical element (2, 3) is provided, in the border region which is to be retained, with a beveled surface (6) inclined in the direction of the mount (1). The mount (1) has a groove (4) which is open axially in front of the optical element (2, 3). A ring element (5) which is elastically deformable in the axial direction is pressed in between the beveled surface (6) and groove (4). The angle of inclination of the beveled surface (6) is between 40° and 50°. The boundary (11′) of the groove (4) in the region of the optical element (2, 3) is level with a bevel edge (8), which is oriented toward the mount (1), and the boundary (11) of the groove (4) in front of the optical element (2, 3) is undercut at an angle of from 10° to 15°. The depth of the groove (4) is greater than the radius of the ring element (5) by from 0.15 to 0.2 mm, and a free opening between a bevel edge (10), which is located on the optical element (2, 3) toward the center, and the front edge (12) of the undercut boundary (11) of the groove (4) is equal to 0.8 of the diameter of the ring element (5).
