Document Type and Number:
Japanese Patent JP2011527172
Kind Code:
A
Abstract:
The present application relates to a digital modulator comprising an output stage comprising a number of unit cell arrays, and a sampling stage. The present application relates also to a communication device comprising said digital modulator, a method for digitally modulating and a computer program product. More particularly, the digital modulator comprises an output stage comprising a number of unit cell arrays, wherein the output stage comprises at least one carrier frequency signal input terminal configured to receive a carrier frequency signal. The digital modulator comprises a sampling stage connectable to the output stage, wherein the sampling stage is configured to oversample at least one data input signal. The digital modulator comprises at least one sampling clock generating device configured to generate at least one sampling clock signal depending on the number of arranged unit cell arrays and the carrier frequency signal.
