This paper presents a study of Active inductor based VCOs that helps in increasing the tuning range of the VCO , reduces the chip size and phase noise of the circuit. Study has been done on LC VCOs by replacing the passive inductors with the active one consisting of MOSFET. Design of circuit has been done on Orcade Capture using . 18um technology. power consumption of circuit is 1. 33mW with tuning range of 81%. Tuning range of the VCO is increased because the active inductor cancels out the parasitic capacitance of the circuit.
