On chip 10 Ohm Resistor
Before we look for trimming, let us review the following:3 B) I/ V& \6 k$ f
1. What is the technology used here
8 o( |, t$ Q' d6 y& `, Q2. What type of resistors you have
4 y6 E* h9 Z N) s( R! Q3. What is the sheet resistance/ area
/ k, s! g+ a3 ]# y3 q! {- D4. What are the fluctuation of these resistances over corners and temperature
, R7 v4 G y, Q0 A7 o, r% z3 U3 K! l; A2 m% z5. How much area you have' s9 a6 U7 _( `3 U* x& G
