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
(535) 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 (540). The second circuit portion is then
connected to the first circuit portion (550) and a bias-maximizing code
word is generated at the first circuitry (505). A first DC bias
correction value is then determined that will eliminate a first DC bias
at the first circuit portion (555). 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.
