Abstract
A voltage to current converter is formed of a first current steering mirror which includes first binary weighted current mirror transistors and receives an input voltage signal and converts it to an output current. The converter also is formed of a second current mirror which generates a selectable output current, the second current mirror being formed of second binary weighted current mirror transistors. The output currents of the first current steering mirror and second current mirror are added and the sum is provided to the control input of a current controlled oscillator which can be used in a phase locked loop.
