What are the popular and effective matching methods ?

[power-twq]

Hello, all friends:

In analog circuit design, The high performane

often come from excellent matching,

what are the popular and effective matching methods

for resistor , capacitor, inductos and transistor.

and how these methods assure good matching

when process, power voltage, temperature are variing.

I often think about why ANALOG DEVICE and TI can

design very high performane analog device, why can we

not, what are we lack of???


best regards

Re: matching methos?

I think that "The art of analog layout" contain some topics on matching, they are worth reading.

Re: matching methos?

I think you are right , and the matching not only in layout ,but also in circuit design.
The TI high performance product has its own process surpport such as triming ,with this tech, you can got very high precision reference , this in only one example, and some special process and patent in their own fab such as high voltage ,low rds on ,etc.
