RF pulse-width-modulation generator employing a delay-locked-loop for a wideband transmitter

A delay-locked loop (DLL) based RF-PWM generator is proposed for broadband signal modulation. The approach can be applied to a Cartesian transmitter in combination with a switching output stage. The proposed transmitter architecture is verified in a macro-model simulation, using a signal bandwidth of 40 MHz, at a carrier frequency of 2 GHz.
