Structure for improved cuttent controlled oscillation device and method having wide frequency change

A design structure embodied in a machine readable medium used in a design process, the design structure comprising:

• a current controlled, phase locked loop device, including a phase detector configured to compare a reference frequency to an output frequency of a current controlled oscillator (ICO);
• a charge pump coupled to said phase detector and a low pass filter coupled to said charge pump;
• a voltage to current (V to I) converter coupled to said low pass filter, said V to I converter providing an output current for integral control of said ICO;
• and
• a control circuit coupled to said ICO, said control circuit receiving increment and decrement outputs of said phase detector, wherein said control circuit is configured to provide proportional control of said ICO through an amount of bias current applied to said ICO, said bias current based on the value of said increment and decrement outputs of said phase detector.
