description A method, system, and circuit device for interfacing single-ended charge pump output to differential voltage controlled oscillator (VCO) inputs to yield low duty cycle distortion from a VCO. A single-ended charge pump output is utilized to create a compliment differential voltage leg, while optimally centering the common-mode voltage level to interface to a current starved ring VCO. A replica of the VCO's current starved delay cell is implemented along with negative feedback to generate the compliment differential voltage leg. The single-ended charge pump output is coupled to a first transistor, while a second transistor is coupled to the output of an error amplifier. The error amplifier utilizes negative feedback to bias the second transistor, forcing the output of the replica circuit to equal a reference voltage.
