On chip 10 Ohm Resistor
Before we look for trimming, let us review the following:! b. y- @8 X& [) a `# d& n+ a) z
1. What is the technology used here
! H. S& i; h! D8 a4 o# O( g2. What type of resistors you have9 @9 Z+ a" \+ g2 a
3. What is the sheet resistance/ area! q% R: X/ f3 R1 y2 S0 D
4. What are the fluctuation of these resistances over corners and temperature
( T5 J5 m3 v7 K7 l5. How much area you have. V- T; R3 K3 {+ u) g
% ^( J. e" h& M0 T, k4 |7 W& n( x
Not quite sure one would have a pragmatic solution here.; Z* p& x( d6 W5 M
0 k; Y/ t, m# M2 t9 N5 T
Hopefully these help. |
