Abstract
A modulator and associated method includes a calculation block configured to receive a plurality of digital samples of a modulated baseband signal, and determine time instances associated with predetermined phase crossings of the modulated baseband signal. The modulator further includes a converter circuit configured to generate a data dependent clock signal having rising and falling edges associated with the determined time instances, and a digital to analog converter configured to receive the data dependent clock signal and generate a square wave output signal having transition times associated with the generated data dependent clock signal.
