## A question about the floating bandgap reference in Razavi's book

If VE=Vf & R4=R5, then the current through M10 & M9 are the same & So is M11 &M10 currents -->making Vgs9=vgs11. And lets assume Vgs9 >Vgs11. Then we will have node Ve not equal to Vf, which is not possible with the amp. Actually R4 is not equal to R5; see the original paper which proposed this topology: "A Low-Power Di

## What does TC mean? (Bandgap reference)

Hi, I am reading from Thomas Lee's book on RFIC about bandgap references. It uses an acronym TC and I can't seem to figure it out. "The best we can do is achieve zero TC at one temperature. Further more, in order to achieve this zero TC condition at that one temperature ..." TC= temperature coefficient? Thanks, Tyro

## temperature independent bandgap volatage reference

The design of bandgap references is not trial and error. The theory and design is covered in every IC design book. Keith

## 1.2v bandgap refernce design for LDO

I need some papers about Band Gap reference design for LDO The input voltage is 2v and the gap should output 1.2v for the LDO reference I am using 0.13um tsmc13rf and running simulations in cadence a book other than razafi's ,which i already have, will also be fine Thanks guys

## analog simulation examples using hspice

Hi, I am a newcomer to design analog circuits(such as opamp and bandgap reference). I would like to find some data and websites introducing analog simulations with hspice. Tell me that how to get those source,please. Thank you very much. chinwei

## Reference about designing bias cell (specially gm cell for RF)

razavi has a chapter about bandgap refrences.

## Question for BANDGAP experts:

Hi,jcpu which structure of your BG? I have designed many bandgaps for different process and difference structures. if you use error amplifier, the mismatch of AMP is most influence. do mente analysis you can get the result that the error amplifier input devices mismatch is the bigest. so you coult increase the L and W. the current mirror, BJT a

## bandgap startup circuit reference

Do you know any book or ref to design the startup circuit for bandgap both in cmos and bicmos process. Please advise. thanks

## how can i get the spice parameters of BJT.

I am a student.I want to study bandgap reference.I can get CMOS spice parameters from MOSIS.com.But how can i get parameters of lateral BJT which are compatible with CMOS process?

## Why is it around 1.2V for bandgap design ?

I think 1.2 V is an old concept of the original bandgap reference design, in fact, in current CMOS process, use the parasitic PN junction and current mode circuitry, the temperature independt reference is not limited to 1.2V Regards, Added after 2 minutes: There is a book focus on the bandgap (...)

## bandgap voltage reference

dragonslayer - this is a quite brilliant circuit, where did it come from? i would like to buy the book, or to get a copy of the class notes where this occurrs. can you PM me? in exchange I will solve your problem. this circuit is a very clever implementation of a shunt bandgap reference. It gives an output voltage (at top of R2) of (...)
