State-Space Simulation of LC Ladder Filters

One-dimensional (1-D) pseudoquadrature mirror filters(PQMF’s) have been introduced as a generalization of quadrature mirror,filter (QMF) concepts. U&z; of such filters allows one to split directly thespectrum of an input signal into N equally spaced subbands which can bedecimated by N: 1, then inteipolakd and recombined to reproduce theoriginal signal. In this paper, a detail...

Analysis of Oscillation Amplitude and Phase Error in Multiphase LC Oscillators

Abstract   This work proposes a novel method to find the phase error and oscillation amplitude in multiphase LC oscillators. A mathematical approach is used to find the relationship between every stage's output phase and its coupling factor. To much more general analysis, every stage assumed to have a different coupling factor. The mismatches in LC tanks are considered as the main source of pha...

A Review and Modern Approach to LC Ladder Synthesis

Ultra low power circuits require robust and reliable operation despite the unavoidable use of low currents and the weak inversion transistor operation region. For analogue domain filtering doubly terminated LC ladder based filter topologies are thus highly desirable as they have very low sensitivities to component values: non-exact component values have a minimal effect on the realised transfer...

Extracting Hidden-Photon Dark Matter From an LC-Circuit

We point out that a cold dark matter condensate made of gauge bosons from an extra hidden U(1) sector dubbed hiddenphotons can create a small, oscillating electric density current. Thus, they could also be searched for in the recently proposed LC-circuit setup conceived for axion cold dark matter search by Sikivie, Sullivan and Tanner. We estimate the sensitivity of this setup for hidden-photon...
