1. This is easily done using discrete components by gluing the two transistor cases back-to-back.
   对于分立器件，只要让两个晶体管的管壳粘在一起就可以了。
2. It is not possible to fabricate very high resistances on thin film or IC substrates, and high VALUE discrete RESISTORs are considerably less stable than lower VALUE ones.
   在薄膜或硅片上无法制作高阻值的电阻，另外，高阻值的分立器件电阻器与阻值较低的电阻器相比，稳定性方面也差很多。
