Impedance analyzers find an important role in nanoscience and in biological research as a tool to access electrical and physical parameters of the matter as well as to enhance the read-out performance in sensor applicati

Polar or outphasing radio transmitter architectures promise higher efficiency than their Cartesian counterparts [1], but require the adoption of phase modulators with bandwidth about one order of magnitude wider than the

Flicker noise up-conversion into close-in 1/f3 phase noise is still one of the major issues in the design of CMOS oscillators. Suppression techniques have been recently presented suggesting (i) adoption of a resonant net

Impedance measurements play a fundamental role in biotechnology, serving both as an investigation tool and as a direct detection technique. Tracking impedance over time is extensively used for spatial monitoring, imaging
