  • 零晶体管IC-IC设计一个新高度

    Abstract: We can apply a BiCMOS integrated circuit with only resistors and no transistors to solve adifficult design problem. The mythically perfect operational amplifier's gain and temperature coefficient aredependent on external resistor values. Maxim precision resistor arrays are manufactured together on asingle die and then automatically trimmed, to ensure close ratio matching. This guarantees that theoperational amplifier (op amp) gain and temperature coefficient are predictable and reliable, even withlarge production volumes.

  • 阻抗匹配

    阻抗匹配  阻抗匹配(Impedance matching)是微波电子学里的一部分,主要用于传输线上,来达至所有高频的微波信号皆能传至负载点的目的,不会有信号反射回来源点,从而提升能源效益。  大体上,阻抗匹配有两种,一种是透过改变阻抗力(lumped-circuit matching),另一种则是调整传输线的波长(transmission line matching)。  要匹配一组线路,首先把负载点的阻抗值,除以传输线的特性阻抗值来归一化,然后把数值划在史密夫图表上。  把电容或电感与负载串联起来,即可增加或减少负载的阻抗值,在图表上的点会沿著代表实数电阻的圆圈走动。如果把电容或电感接地,首先图表上的点会以图中心旋转180度,然后才沿电阻圈走动,再沿中心旋转180度。重覆以上方法直至电阻值变成1,即可直接把阻抗力变为零完成匹配。  由负载点至来源点加长传输线,在图表上的圆点会沿著图中心以逆时针方向走动,直至走到电阻值为1的圆圈上,即可加电容或电感把阻抗力调整为零,完成匹配.........

    SPLASH is a c++ class library that implements many of the Perl constructs and data types, including extensive regex regular expression pattern matching. For those not familiar with Perl, it is an excellent scripting language by Larry Wall and is available for most platforms. This Class library provides List, String, Regular Expression, and text manipulation handling capabilities based on those provided in Perl
