Hi,
Where do you need to use these linear resistors and how linear do you need them to be?
I can think of the following few examples, although they are all a little different from each other in terms of context:
1. Large Ron (upto 100 MOhm) using CMOS: Vittoz et. al., JSSC, June '88 (High Performance, Crystal Osc..., Section IV)
2. Linear current division: Bult, Geelen, JSSC, Dec. '92(An Inherently Linear & Compact Current Division Technique)
3. Linear Gm: Gilbert, JSSC, Jan. '98, (The multi-tanh principle....); this is with BJTs but you can use MOS biased in weak inversion.
Hope this helps.
Regards Vivek
