摘      要：An improved compensation method for an all-standard-cell voltage-controlled oscillator (VCO)-based ADC is presented in this Letter. The proposed compensation uses closed-form orthogonal polynomials bases instead of power series ones. With these more powerful bases, the cross interaction between different basis is eliminated which leads to better resolution, lower order of compensation series, and shorter convergence time of the adaptive algorithm.
