A novel algorithm is presented that can resolve frequency ambiguity that arises from sampling a set of signals spanning more than a single Nyquist zone. The method uses two samplers, each sampling the same input signal with different (non-integer mul

Highly efficient switch-mode class-E power amplifiers (PAs) are sensitive to load impedance variations. For voltage standing wave ratios (VSWRs) up to 10:1, the peak switch voltage and the average switch current can increase by a factor of 1.7 and 2.

Power amplifiers (PAs) need digital predistortion (DPD) linearization to handle high-order complex modulation schemes in next-generation communication systems. While load variation is inevitable, DPD is generally designed considering only the nominal

A two channel 65 nm CMOS RF-waveform characterizer is presented that enables multi-harmonic Adaptive Matching Networks (AMN) or Adaptive Digital Pre-Distortion (ADPD) in RF-power amplifiers. The characterizer measures the DC component and the first 3
