An apparatus for saving power in an field programmable gate array (FPGA) in an optical communication device is provided. The apparatus includes at least one ring oscillator having an operating frequency disposed inside the FPGA, a core voltage switching unit configured to supply a core operating voltage to the FPGA, and control logic configured to adaptively output an adjusted new core voltage to the FPGA via the core voltage switching unit. The control logic is configured to output a core voltage control signal to the core voltage switching unit based on the operating frequency of the at least one ring oscillator. The core voltage switching unit is further configured to supply the adjusted new core voltage to the FPGA in accordance with the core voltage control signal.
