Log-domain filtering: an approach to current-mode filtering

IEE Proceedings G Circuits, Devices and Systems, 1993
A novel approach to filter design, based on Adams' [1] ‘log-domain’ filters, is proposed that yields a truly current-mode circuit realisation. Adams' idea, which was introduced in a limited context, is generalised to permit a complete distortionless synthesis procedure, which results in circuit implementations readily realisable using complementary ...

Current mode biquadratic universal filter

2015 IEEE Asia Pacific Conference on Postgraduate Research in Microelectronics and Electronics (PrimeAsia), 2015
A current mode universal filter using current controlled differential difference current conveyor transconductance amplifier (CCDDCCTA) is discussed. The filter provides important and desirable features : (i) Uses only one CCDDCCTA and two capacitors, (ii) One can get low pass (LP), band pass (BP), high pass (HP), notch (NF) and all pass (AP) current ...

Low-voltage current-mode filters

Proceedings of the 39th Midwest Symposium on Circuits and Systems, 2002
A novel analogue continuous-time current-mode filter synthesis technique is proposed based on a transformed set of state-equations that allow the utilization of only current-mode linear lossy-integrators, implemented using standard current mirrors; also a novel current-mode gyrator is introduced.

Current‐mode biquadratic filter using DO‐CCCDBAs

International Journal of Circuit Theory and Applications, 2008
AbstractThis paper presents a current‐mode universal biquadratic filter performing three functions; low pass, high pass and band pass, based on dual‐output current‐controlled current differencing buffered amplifiers (DO‐CCCDBAs). The features of the circuit are that the quality factor and pole frequency can be tuned independently via the input bias ...

A CMOS low power current-mode polyphase filter

Proceedings of the 2009 ACM/IEEE international symposium on Low power electronics and design, 2009
A new CMOS polyphase filter based on current followers is presented. Adoptions of such relatively simple building blocks and a filter structure employing minimum number of active elements, have lead to low power solution. The proposed filter is used to construct a 6th-order polyphase fully differential filter suitable for Bluetooth low-IF receiver ...

Current-Mode Continuous-Time Filters

1995
A low-voltage high-frequency CMOS fully-balanced filtering technique is presented. The low internal voltage characteristic of current-mode circuits allows the operation at power supply voltages as low as 3-V with high dynamic range. The integrator time-constant is determined by a MOSFET small-signal transconductance and an additional non-critical ...

Current-mode leapfrog ladder filters using CDBAs

2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003
In this paper, a possible realization of a current differencing buffered amplifier (CDBA) in the low-voltage operation is proposed. A leapfrog simulation of the current-mode ladder network using the CDBAs as active circuit building blocks is then introduced.

New current-mode biquad filter

International Journal of Electronics, 1992
A new current conveyor-(CC-)based active biquadratic filter configuration is proposed. The proposed structure offers the following advantageous features in contrast to the previously known CC-based current mode filters: (i) the realization of all the five generic filter functions (namely, low-pass, band-pass, high-pass, notch and all-pass) from the ...

Current-Mode Fractional-Order Filters

2017
This chapter presents a current-mode technique for realizing fractional-order filters, where low-voltage current mirrors are employed as active elements. A novel topology of a current mirror, which is able to realize large time-constants is introduced.
