Eigen Oscillations of LC Ladder Loop Circuits

Systematic Implementation Method of Lc-ladder Filters by Mo-cccii Circuits

The paper implements the well-known leapfrog method of LC-ladder filters simulation by circuits employing only multiple outputs second-generation current controlled conveyors (MO-CCCII) and grounded capacitors. The proposed method is general, because on a hand it implements any type of frequency behaviours and on the other side both all pole and finite-transmission-zeros passive filters are emu...

Simulation of LC Ladder Filters Using Opamps

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...

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...

Log-Domain Filters Based on LC Ladder Synthesis

A design method is proposed for the synthesis of linear, high-order, continuous-time filters using a unique translinear integrator circuit. Unlike previous attempts at incorporating translinear circuits into filter design, the proposed theory makes explicit use of the exponential nature of the bipolar transistor. This technique is based on the operational simulation of LC ladders. A 5th-order C...
