A new realizable structure to improve VCO linearity
FM nonlinearity is the main obstacle to improve the performance of a good many VCO applications. In the paper, a universal correction model is brought up and based on the model the sources of dominant error in the correction process are analyzed. To decrease errors produced in the carrier frequency-transfer segment, a dividing frequency ˉdelay structure of high performance, low cost is brought up based on ideas from some existent correction structures. The structure has an innovative feature, dividing frequency relativity. Simulation proves that the new structure and feature has excellent noiseproof performance and deserves further research.
