comparison of CMOS and BJT

[adam79416]

I am looking forward the answer of the question upstairs. what is the LinMOS?

 

[djalli]

what is the LinMOS?

It is proprietary of Texas Instruments. They say it offers extremely high input impedance and low input bias and offset currents. They say a lot of features associated with bipolar technology are available with LinCMOS operational amplifiers without the power penalties of traditional bipolar devices.

So far I am pleased with performance of their opamps.

why can a bipolar give you higher precision than a MOSFET ?

 

[qutang]

bipolar need more time to fab.

 

[Puppet1]

how does that affect precision ?

 

[vonleo]

I think CMOS tapeout(around 1-2 month) is faster than bipolaris (more than 3 months?) but CMOS is less reliable than bipolar. I don't know much about the technology, I guess something about the quasi-static stuff in the channel?

how does that affect precision ?

 

[eezou]

Transconductance of bipoar is larger than mos device

u can have a look at the following doc......may be help ful.....

bjt is quite faster than cmos
