This brief reports a compact DC-110GHz single-pole single-throw (SPST) switch in 22nm FDSOI CMOS technology. The adopts solely three n-MOSFETs, two of them with special device option to reduce the substrate parasitic effects, and third n-MOSFET parallel gate resistance series improve isolation. Unlike prior wideband mmwave switches, it does not make use any large passive components, such as spi...

We consider two electric RLC resonance networks that are equivalent to quantum billiards. In a network of inductors grounded by capacitors, the eigenvalues of the quantum billiard correspond to the squared resonant frequencies. In a network of capacitors grounded by inductors, the eigenvalues of the billiard are given by the inverse of the squared resonant frequencies. In both cases, the local ...

We present fully integrated high-performance voltage-controlled oscillators (VCOs) with on-chip microelectromechanical system (MEMS) inductors for the first time. MEMS inductors have been realized from the unique CMOS-compatible MEMS process that we have developed to provide suspended thick metal structures for high-quality ( ) factors. Fully integrated CMOS VCOs have been fabricated by monolit...

High performance magnetic heads, inductors and transformers, indispensable to information technology encompassing from information storage, portable power delivery, to wireless communication, require soft magnetic films with low coercivities, high permeability, and large ferromagnetic resonance frequencies. The Fe-Co-N-based films have a ferromagnetic resonance frequency of >1 GHz at zerobias f...

This paper presents a systematic study of compact and reconfigurable periodic structure in GaAs MMIC technology. Compactness is achieved by the introduction spiral inductors conventional unit cell without disturbing reactive loading mechanism. The proposed architecture exhibits 28.3% wider stopband with 62.6% smaller footprint compared to structure. compactness bandwidth improvement explained h...

This paper generalizes the idea of “multiple resonance networks” to energy transfers between inductors and between capacitors and inductors, extending the theory about this class of LC lossless circuits. The networks discussed have the property of transferring all the energy initially stored in a particular capacitor or inductor in an LC network to another element in the network, through a line...

Coupled inductors are described in Section 11.9 of Introduction to Electric Circuits by R.C. Dorf and J.A Svoboda. In particular, Table 11.14-1 summarizes the equations that represent coupled inductors in the frequency domain. Circuit analysis in the frequency domain is described in Sections 10.6 thru 10.11. Table 10.7-1 summarizes the correspondence between the time domain and the frequency do...

Introduction In MR Imaging the RF coupling properties of reactive components like inductors and capacitors used for building Phased Array Coils are very important. Ideally these components must have lump circuit characteristics only, without manifesting any stray radiation. These goals might appear to be contradictory since inductors and capacitors with higher inductances and capacitances respe...

Thiopurine methyltransferase (TPMT) is implicated in the metabolism of azathioprine. The consequences of differential TPMT activity induction by azathioprine on the long-term results after renal transplantation were investigated. The erythrocyte TPMT activity in 82 patients on days 0, 7, and 30 was prospectively evaluated. Because various patterns of TPMT activity variation were noted, the popu...
