Title: VCO LC tank
Post by Victor Chen on Jul 28^th, 2004, 12:10pm

Hi.

I am new to VCO design. I am trying to design a diff. VCO in CMOS process.
Why it seems that people use parallel tank much often than series tank?

Thx.

Vic

My guess is that a parallel resonator easily allows you to provide a bias current to the transistors.
