In this paper four different topologies of LC tank VCOs for low power consumption and low phase noise are studied. After comparing four different topologies,it is seen that LC tank VCO with pseudo resistance provides minimum phase noise i. e. -125. 5 DBc/Hz @1MHz, and differential cross coupled LC tank VCO provides minimum power consumption i. e. 0. 675 mW at 180 nm technology.
