Voice Activity Detection (VAD) is a technique used to identify the presence of human voice in an audio signal. It is implemented as an always-on component in most speech processing applications. As speech is absent most of the time, this component ty

We present a simple and useful figure of merit (FoM) with which to evaluate the performance of simultaneous-multi-beam (SMB) transmit (TX) antenna arrays. The FoM builds upon the power-aperture product and effective isotropic radiated power for singl

Hard-switched mixers have attractive linearity and noise properties, but are plagued by spurious responses due to the harmonic content of square-wave local oscillator (LO) signals. Harmonic rejection mixers (HRMs) reject (some of) these responses and

We propose a fast and simple method to accurately determine the compressing stage in a two-stage amplifier system based on reverse intermodulation and hot S-parameter measurements. The method uses no specialized hardware and needs little reconfigurat

A single-trim, highly accurate Colpitts-based frequency reference is presented. Our analysis shows that the Colpitts-topology outperforms the cross-coupled LC -topology in terms of temperature stability. Measurements on prototypes in a 0.13- $\mu \te

The modern spectral, and thereby linearity, requirements force 5G phased-array transmitter systems to operate at reduced power efficiency, as they can no longer use voluminous filtering. To reduce the linearity requirements of the transmitter, we con

Power amplifier nonlinearity introduces intermodulation distortion when transmitting dual-tone signals from an antenna array. To reduce distortion levels and increase output power for dual-tone systems we propose to densely interleave two antenna arr
