We presents a new^generalised power efficient ADPLL design & Simulation^using Verilog*. Xilinx ISE 10.1 Simulator is^used for simulating Verilog Code and is synthesized using Cadence RTL compiler using gpdk 45 nm technology. To validate its functionality, verification and simulation is done by using^the Cadence IES (Incisive Enterprise Simulator) tool. This paper gives the details of basic building^blocks of the absolute ADPLL*design. And the planned power optimized clock gating technique*that
