POLAR TRANSMITTER FOR COMPENSATING TIME-DELAY, OPERATION METHOD THEREOF AND PORTABLE DEVICE INCLUDING THE SAME

摘要

PURPOSE: A polar transmitter with a time delay compensation function and an operating method thereof, and a mobile terminal with the same are provided to prevent a time delay when signals are transmitted/received. CONSTITUTION: A baseband signal processing unit(210) outputs a pulse modulation signal for detecting a time delay. An amplitude modulating unit(220) generates an amplitude modulating signal by the pulse modulation signal. A phase modulating unit(230) generates a phase modulating signal by the pulse modulation signal. A time delay compensating unit(250) differentially amplifies the difference between an output of the amplitude modulating unit and an output of the phase modulating unit.
