Novel Microwave Negative Capacitance. Application to a Wide-Range Tunable Capacitance

Author: Svilen Kolev, Bruno Delacressonnière, Jean-Luc Gautier

Novel Microwave Negative Capacitance. Application to a Wide-Range Tunable Capacitance Svilen Kolev, Bruno Delacressonnière, Jean-Luc Gautier ENSEA-EMO, Cergy-Pontoise, France Abstract - In this paper we propose an active broadband MMIC circuit simulating a negative capacitance. It is based on a Negative Impedance Converter (NIC). A prototype has been fabricated using 0.25 µm pHEMT technology. The

FFT and Swept Spectrum Analysis in Microwave Measurements

Author: Ajit Ramachandran

FFT and Swept Spectrum Analysis in Microwave Measurements Ajit Ramachandran Agilent Technologies, Santa Rosa, California, USA ajit_ramachandran@agilent.com Abstract ­ Accuracy, speed, and dynamic range are important considerations, among which tradeoffs are typically made for a given measurement. We present that FFT (fast Fourier transform) spectrum analysis is inherently less accurate than Swep
