Abstract: For example, an apparatus may include an input to receive an input signal in a first voltage domain; a multi-mode power amplifier switchable between a plurality of power modes to generate an output signal based on the input signal; and an output to provide the output signal. For example, the multi-mode power amplifier may be configured to provide the output signal in the first voltage domain at a first power mode, and to provide the output signal in a second voltage domain at a second power mode. For example, a maximal voltage of the second voltage domain may be at least two times a maximal voltage of the first voltage domain.

Abstract: For example, a phase shifter may include an input to receive an input clock signal having an input frequency and an input phase. For example, the phase shifter may include a quadrature phase-shift generator configured to generate a first signal and a second signal based on the input clock signal, the first and second signals having the input frequency, wherein a phase of the first signal is based on the input phase, wherein a phase of the second signal is shifted by a quadrature phase-shift relative to the phase of the first signal. For example, the phase shifter may include an output to provide an output based on the first signal and the second signal.

Abstract: Various embodiments provide systems, devices, and methods for a multi-core digital power amplifier with an unbalanced power combiner. In one example, two or more cores are combined with a transformer section that has a first coupling coefficient and another two or more cores are combined with a second transformer section that has a second coupling coefficient that is different than the first coupling coefficient. The outputs of different cores may be cross-coupled with the primary inductors of the transformers. The digital power amplifier may provide an output power that is flat over a relatively wide operating range. Other embodiments may be described and claimed.

Abstract: A closed loop transmitter (Tx) calibration system is disclosed. The closed loop Tx calibration system comprises a transmitter circuit configured to generate a Tx output signal at a Tx output frequency based on a Tx local oscillator (LO) signal. The closed loop Tx calibration system further comprises a loop back (LPBK) receiver circuit coupled to the transmitter circuit and configured to downconvert the Tx output signal at the Tx output frequency to form an LPBK baseband signal at an LPBK intermediate frequency (IF), based on an LPBK LO signal. In some embodiments, the LPBK IF frequency is different from zero. In some embodiments, the closed loop Tx calibration system further comprises an LO generation circuit configured to generate the Tx LO signal and the LPBK LO signal from a single phase locked loop (PLL) source, based on utilizing a digital to time converter (DTC) circuit.

Abstract: A method and apparatus for determining a difference between signal edges in two signals includes a multiple stage converter where each stage determines which of the two signals has an earlier signal edge, outputs a value corresponding to that determination, and then applies a delay to the earlier signal that is equal to half of the delay applied by the next previous stage. The stages examine smaller and smaller intervals to the sought-after signal edge. Each stage includes a plurality of logic elements. If all logic elements in the stage output the same signal, the edge position is clear. If some of the logic elements in the stage vote differently than others in the state due to differences in setup time for the different elements, the edge location has been found within the sensing band of the stage.

Abstract: For example, a transmitter, e.g., for a wireless communication device, may be configured to transmit a wideband Radio Frequency (RF) Transmit (Tx) signal having a wide bandwidth of at least 80 Megahertz (MHz). For example, the transmitter may be configured to generate the wideband RF Tx signal having the wide bandwidth based on a baseband signal. The transmitter may be configured to generate the wideband RF Tx signal including a suppressed third harmonic and a suppressed fifth harmonic.
