时间交错模数转换器(TIADC)的非理想电路实现引起的非线性行为严重降低了TIADC的性能。在大多数情况下,静态非线性是TIADC非线性行为的主要组成部分,本文提出了一种基于模型逆策略的校正方法来补偿TIADC中的静态非线性。本文提出的周期时变自适应校正方法可以直接估计逆多项式模型的系数,并捕捉到环境变化时非线性参数的变化。本文提出的方法也适用于用Volterra级数变换多项式的动态非线性问题。仿真结果表明了该方法的有效性和鲁棒性。
The nonlinear behaviors of time-interleaved analog-to-digital converter (TIADC) caused by non-ideal circuit implementations degrade performance of TIADC significantly. This paper proposes a calibration method based on model inversion strategy to compensate for static nonlinearities in TIADC, since static nonlinearities are the major compositions of the nonlinear behaviors in most situations. The proposed periodic timevarying adaptive calibration method can estimate coefficients of inverse polynomial model directly and capture variations of the nonlinear parameters when environment changes. The method proposed in this paper is also applicable to dynamic nonlinearities by changing polynomial with Volterra series. Simulation results show the effectiveness and robustness of the proposed method.
