Abstract
A delay interpolating voltage controlled oscillator (VCO) is provided. The delay interpolating VCO includes an input for receiving differential control input. A non-linear current steering circuit is coupled to the input for generating a non-linear delay responsive to the differential control input. A frequency signal is provided at a VCO output responsive to the differential control input and the non-linear delay with the frequency signal being linearly related to the differential control input.
