ABSTRACT:
A digital signal having a plurality of bits is received by a converter. Two of the bits, the most significant bit and a second bit which is not the most significant bit or the second most significant bit, are tapped from the output and used as a feedback signal. These two bits are also used to form an analog output signal. The two bits are attenuated using a weighted network and then summed to provide the analog output signal.
