The trans-admittance-mode (TAM) might act as a transforming bridge for voltage-mode to current-mode conversion. In this study a new low voltage operated electronically tunable TAM biquad filter structure realizing all the seven standard filtering functions namely; low-pass (LP), band-pass (BP), high-pass (HP), regular-notch (RN), low-pass-notch (LPN), high-pass-notch (HPN) and all-pass (AP) fro...

A log-domain current-mode quadrature sinusoidal oscillator based on lossless integrators is presented. The circuit is a direct realization of a first-order differential equation for obtaining the lossy and lossless integrators. Each of the log-domain lossless integrators is realized by using only NPN transistors and a grounded capacitor for achieving low-power and fast response. The proposed os...

The paper deals with the problem of designing digital circuits based on the current-mode gates novel digital elements operating with constant, continuous power supply current. The purpose is the provision of a high level of the noise immunity of the chips which compose both analog and digital circuits. The logical properties of this gate basis and several identities for conversing expressions f...

This paper describes a current controllable current-mode universal filter with three inputs and one output using multioutput current-controlled current conveyors (MOCCCIIs). The proposed circuit consists of the minimum number of active and passive components, i.e. two MOCCCIIs and two grounded capacitors; simultaneous realization of all the standard filtering functions; independent current-cont...

Combination of A/D-D/A converters allows implementing multiplier/divider operations. An efficient design based on continuous-time, current-mode, dividing-algorithmic converters is presented in this paper. It offers high speed and capability of low voltage operation, and it is suitable for applications of low or middle resolution (below 9 bits). In addition, the division result is given in both ...

Motivated by advantages of current-mode design, this brief contribution explores the implementation of weight matrices in neuromemristive systems via current-mode memristor crossbar circuits. After deriving theoretical results for the range and distribution of weights in the current-mode design, it is shown that any weight matrix based on voltage-mode crossbars can be mapped to a current-mode c...

Analogue first, second and high-order all-pass active filters in the current mode, with constant group delay and magnitude responses, are presented in this paper. These filters are based on a modification of the multi-loop feedback canonical structures using signal flow graphs. Implementations by multi-output transconductors, namely classical OTAs and novel CDTAs are given.
