“Distortion-Free” Varactor Diode Topologies for RF Adaptivity
نویسندگان
چکیده
Varactor diode-based circuit topologies, which can act as high-Q “distortion-free” tunable capacitive elements, are presented. These diodes are implemented in a novel ultra low-loss silicon-on-glass technology, with resulting measured Q's of over 200 at 2 GHz. The measured IM3 improvement compared to traditional single varactor tuning techniques is greater than 30 dB. Index Terms — Distortion, impedance matching, losses, tunable filters, tuners, varactors.

Design and Analysis of Frequency-Tunable Amplifiers using Varactor Diode Topologies
The design of frequency-tunable amplifiers is investigated and the tradeoff between linearity, efficiency and tunability is revealed. Several tunable amplifiers using various varactor diode topologies as tunable devices are designed by using loadpull techniques and their performances are compared. The amplifier using anti-series distortion-free varactor stack topology achieves 38% power added e...

Electronic control of microwave antennas and circuits is usually based on the use of reverse biased semiconductor junctions. Optical control of such circuits has been by directly illuminating the active (depletion) regions of the semiconductor junctions. In this paper we report indirect optical control of microwave antennas and circuits using a photovoltaic array that generates a light dependen...
متن کاملElectro-Static Discharge Protection Design for V-Band Low-Noise Amplifier Using Radio Frequency Junction Varactor
The RF junction varactors are employed as electro-static discharge (ESD) protection devices and co-designed with 60GHz low-noise amplifier (LNA) fabricated in a 65-nm CMOS technology. The junction varactor acts as an ESD diode to bypass ESD current during ESD zapping, and also utilized as a capacitor to be a part of input matching network of the LNA in normal RF operation. By transmission line ...
متن کاملVARACTOR DIODES The Nuts and Bolts of Tuning Varactors
M any electronic systems must be tuned through the variation of reactance of one or more circuit elements. In these applications it is often desirable to perform this tuning under electronic rather than manual control. Tuning varactor diodes, which are pn junction devices that act as voltage controlled variable capacitors, can perform this function, and are used in a wide range of product appli...
متن کاملOutput-Conductance Transition-Free Method for Improving Radio-Frequency Linearity of SOI MOSFET Circuits
In this article, a novel concept is introduced to improve the radio frequency (RF) linearity of partially-depleted (PD) silicon-on-insulator (SOI) MOSFET circuits. The transition due to the non-zero body resistance (RBody) in output conductance of PD SOI devices leads to linearity degradation. A relation for RBody is defined to eliminate the transition and a method to obtain transition-free c...
