Abstract
Technologies for duty cycle distortion (DCD) estimation are described. A transmitter includes a first output driver comprising a first complementary metal-oxide semiconductor (CMOS) amplifier and a first attenuator coupled to an output of the first CMOS amplifier. The first CMOS amplifier receives an input signal and outputs an intermediate signal to the first attenuator. The first attenuator receives the intermediate signal and outputs an output signal having a signal swing that is less than a signal swing of the input signal. A first duty cycle correction (DCC) loop is coupled to the first output driver. The first DCC loop estimates first DCD in the intermediate signal output by the first CMOS amplifier.
