Abstract
A method is provided for reducing a DC bias in a receiver. This method includes isolating a second circuit portion from a first circuit portion () and determining a second DC bias correction value for the second circuit portion that will eliminate a second DC bias at the isolated second circuit portion (). The second circuit portion is then connected to the first circuit portion () and a bias-maximizing code word is generated at the first circuitry (). A first DC bias correction value is then determined that will eliminate a first DC bias at the first circuit portion (). The bias-maximizing code word is formed such that: a first integrated value of a first half of the bias-maximizing code word has a positive value, and a second integrated value of a second half of the bias-maximizing code word over half of the code word length has a negative value.
