Abstract
A proximity integrated circuit card bias adjustment. In one example, a decoding circuit, having an decoding range, for translating a data-frame signal having an information portion and a bias portion into an output code; and a bias adjust circuit coupled to receive the output code from the decoding circuit, and adjust the bias portion of the data-frame signal such that the output code is within the decoding range is disclosed. In another example, a method for proximity integrated circuit card bias adjustment, comprising: translating a data-frame signal having an information portion and a bias portion into an output code; and adjusting the bias portion of the data-frame signal such that the output code is within a decoding range is disclosed.
