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(Impedance Matching)是微波電子學里的一部分,主要用于傳輸線上,來達至所有高頻的微波信號皆能傳至負載點的目的,不會有信號反射回來源點,從而提升能源效益。 大體上,阻抗匹配有兩種,一種是透過改變阻抗力(lumped-circuit Matching),另一種則是調整傳輸線的波長(transmission line Matching)。 要匹配一組線路,首先把負載點的阻抗值,除以傳輸線的特性阻抗值來歸一化,然后把數值劃在史密夫圖表上。 把電容或電感與負載串聯起來,即可增加或減少負載的阻抗值,在圖表上的點會沿著代表實數電阻的圓圈走動。如果把電容或電感接地,首先圖表上的點會以圖中心旋轉180度,然后才沿電阻圈走動,再沿中心旋轉180度。重覆以上方法直至電阻值變成1,即可直接把阻抗力變為零完成匹配。 由負載點至來源點加長傳輸線,在圖表上的圓點會沿著圖中心以逆時針方向走動,直至走到電阻值為1的圓圈上,即可加電容或電感把阻抗力調整為零,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
