Title: Ring vco architecture selection
Post by summi on Sep 8^th, 2013, 1:19pm

Dear Forum,
I am new to VCO design, generally any delay cell works for ring vco but i have seen several designers choosing inverter based and several choosing differential pair based VCO. Since inverter delay is sensetive to vdd or vss compared to differential pair, why people are using inverter based VCO, though both designs have regulator

Br,
