1.前言所谓超齐纳是一个集成电路,即在一个很小的硅片上含有一个掩盖的齐纳结,一个加热器和两个检测晶体管。它有一个数据表(LT21000)以保证电压随时间有很低的噪声和很小的变化,典型噪声值为2uVkh~(-1/2)。对于一个7V 装置,该值约为0.3×16~(-6)/月或1× 1. Introduction The so-called super-Zener is an integrated circuit that contains a cover-up Zener junction, a heater, and two sense transistors on a tiny piece of silicon. It has a datasheet (LT21000) to ensure very low and very small voltage variations over time, with a typical noise value of 2uVkh -1. For a 7V unit, the value is about 0.3 × 16 -6 / month or 1 ×
