Abstract
Devices and methods of compensating for a bandpass filter are generally described. A DTx includes a BPF from which an output signal is produced and a DFE having a zero crossing (ZC) pre-distorter (ZCPD). The ZCPD compensates for ZC distortion from a desired analog signal caused by the BPF. The ZCPD adjusts a DTC code word to generate a DTx output signal to be applied to the BPF. The compensation is dependent on a magnitude of the square wave immediately prior to and after the ZC. The compensated DTC and a DPA code word are used to generate the DTx output signal. The compensation produced by the ZCPD is free from compensation for non-linear responses to the DTC and DPA code words.
