Tunable current-mode log-domain universal filter

Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010
This paper describes the design of a current-mode universal filter based on log-domain filtering concept. The circuit is a direct realization of a first-order differential equation for obtaining the two integrators loop structure. Lossless integrators are realized by log-domain lossy integrators.

Adaptive Bandwidth PLL with Compact Current Mode Filter

2006 IEEE International Symposium on Circuits and Systems, 2006
This paper presents a compact self-biased current-mode filter (CMF) PLL architecture, which uses relative ratio of charge-pump currents (I/sub cp2/ / |I/sub cp2/-I/sub cp1/|) to obtain a capacitor multiplier. Compatible with self-biased CMF, a modified charge pump switches structure is proposed to reduce phase offset and current activating time.

Current‐mode filters based on current mirror arrays

International Journal of Circuit Theory and Applications, 2007
AbstractA technique is proposed for obtaining current‐mode filters based on current mirror arrays that operate as unity gain current amplifiers. These amplifiers by properly driving capacitors realize active lossless integrators which are the basic active elements for the derivation of filters according to the leapfrog method. Due to the fact that both

A Current-Mode Universal Filter with CCIIs

Journal of Circuits, Systems and Computers
A current-mode universal filter based on the second-generation current conveyors (CCIIs) is developed in this study. The developed filter consists of two positive-type single-output CCIIs, one negative-type single-output CCII, two grounded resistors, one floating resistor and two grounded capacitors. It provides high output impedance currents.

Generation of current mode filters using NAM expansion

International Journal of Circuit Theory and Applications, 2011
AbstractSystematic synthesis method to generate a family of current mode band‐pass–low‐pass circuits based on nodal admittance matrix (NAM) expansion is given. Eight equivalent circuits are obtained, five of them are new. Each of the generated circuits uses two grounded capacitors and three grounded resistors and two balanced output current conveyor ...
