Introduction
RF circuits generally have many passive components, R, C , and L. 2/19
IC resistors with low self-capacitance and TC are hard to come by
(high voltage coecients, loose tolerance, and a limited range of
values.)
Capacitors with high Q and low TC are available, but tolerance
are relatively loose (e.g. 20% or worse).
Inductors larger than about 10 nH consumes signicant die area
and have relatively poor Q (typically below 1……
