ABSTRACT:
A design structure for a programmable interpolative voltage controlled oscillator (VCO) with adjustable frequency range output is provided. Programmable delay cells whose size is modifiable based on control inputs to the programmable delay cells are utilized. A different set of control inputs may be provided to programmable delay cells of an inner sub-ring from the set of control inputs provided to programmable delay cells of a main ring of the VCO. The minimum frequency output of the VCO is governed by the main ring programmable delay cell strength with the maximum frequency output of the VCO being governed by a ratio of strengths of the main ring programmable delay cells to the inner sub-ring programmable delay cell. By modifying the control inputs to the inner sub-ring and main ring programmable delay cells, the minimum and maximum frequency outputs, and thus the range between these two frequency outputs, are made programmable.
