本文描述了以不同组数的读出线并组方式,对磁心读出放大器进行了设计。读出线并组放大器通过在不同机器上所做的实验数据表明,该技术是可行的。这种放大器的特点是以较少的元件为手段来提高放大器的可靠性。由于线性组件在工艺上难以避免的电参数误差而使放大器产生失调,因此采用了组件外引线的方法,把工艺上难度大的元件引到组件外面,以备对放大器灵活地进行匹配与调整,从而达到提高组件的成品率之目的。
This paper describes the design of a core sense amplifier with a different number of readout lines in parallel. Reading the line and grouping the amplifier The experimental data on different machines show that this technique works. This amplifier is characterized by fewer components as a means to improve the reliability of the amplifier. Because the linear component in the process is difficult to avoid the electrical parameters of the error amplifier misunderstood, so the use of components outside the lead method, the process is difficult to lead the components outside the components in preparation for the amplifier to be flexible to match and adjust, So as to achieve the purpose of improving the yield of the component.
