Design and Stability Analysis Techniques for Switching-Mode Nonlinear Circuits: Power Amplifiers and Oscillators [PDF]

, 2006
A design technique for kW level switching mode power amplifiers is presented. Several push pull pairs, independently tuned to Class E/Fodd, are combined by a distributed active transformer.

Global Navigation Satellite Systems disciplined oscillator synchronisation of multistatic radar

IET Radar, Sonar & Navigation
A fundamental challenge in the practical implementation of multistatic radar systems (MSRS) is the requirement for precise time and frequency synchronisation between the spatially separated radar nodes.

Biodegradable and Edible Milli‐Fluidic Logic Circuits

Advanced Materials Technologies, EarlyView.
Fully biodegradable and edible fluidic circuits are developed using gelatin‐based valves that operate at low pressure. Logic gates, a one‐bit memory, and a ring oscillator are demonstrated, showing that biodegradable materials can perform computation and control.

Channel Estimation and Data Detection in the Presence of Phase Noise in MIMO-OFDM Systems With Independent Oscillators

IEEE Access, 2017
In this paper, we propose the mitigating scheme to reduce the effects of phase noise in multi-input multi-output-orthogonal frequency division multiplexing system with independent oscillator in each RF chain.

Deterministic Transferable Planar Dielectric Mirrors for Investigating Strong Light–Matter Coupling

Advanced Optical Materials, EarlyView.
Transferable dielectric distributed Bragg reflectors enable the deterministic assembly of high‐quality planar microcavities while maintaining the intrinsic properties of quantum materials during fabrication. The resulting structures exhibit robust exciton‐photon coupling in monolayer WS2${\rm WS}_{2}$ from cryogenic to room temperature, establishing a ...

Resonant response functions for nonlinear oscillators with polynomial type nonlinearities [PDF]

, 2013
In this paper we consider the steady-state response of forced, damped, weakly nonlinear oscillators with polynomial type nonlinearities. In particular we define general expressions that can be used to compute resonant response functions which define the ...

LO Generation Techniques for Millimeter-Wave Receivers

IEEE Open Journal of the Solid-State Circuits Society
Millimeter-wave radios hold promise for supporting high data rates in wireless communication. A key challenge in the development of these radios relates to the generation of the local oscillator (LO) waveform(s) necessary for upconversion and ...
