A current-mode DTCNN universal chip
Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002The paper describes an analog current mode realization of Discrete-Time Cellular Neural Networks (DTCNNs) with high cell density, which have local analog and local logic memory. Hence, some important parts of the CNN Universal Machine concept are implemented.

Current-mode frequency discriminators
42nd Midwest Symposium on Circuits and Systems (Cat. No.99CH36356), 2003Current-made frequency discriminators are introduced which can be realized by cascading current-mode sections, and design information is provided. A fifth order design example is given which provides 24 dB/octave attenuation at high frequencies. This circuit uses only three current conveyors.

CMOS Current-Mode Companding Divider
IEICE Transactions on Electronics, 2009A CMOS current-mode companding divider is presented. Currents of both dividend and divisor are compressed into log-domain. Then the logarithm current of divisor is subtracted from the logarithm current of dividend. After expanding the subtraction result, the division function could be achieved.

As pointed out in Chapter 6, the conventional PWM converters are in essence feedback control systems and can therefore be treated accordingly with the available analytical tools, provided some additional steps are taken. The major theme of these types of treatments center, in almost all cases, around two performance merits: output voltage DC regulation

3V high-frequency current-mode filters
1993 IEEE International Symposium on Circuits and Systems, 2002A fully differential current mode integrator circuit and its cascode variants are presented for use in low voltage, high frequency signal processing applications. It is shown that good linearity is achieved with signal levels up to the current bias, the equivalent of voltage mode rail-to-rail operation.

Current-Mode Instrumentation Amplifiers Based on Various Current-Mode Building Blocks
2018In this chapter current-mode instrumentation amplifiers (CMIAs) implemented with different current-mode building blocks are discussed. Various structures are classified into four categories based on their input and output signals, i.e. current input current output (I-I) or pure CMIA, current input voltage output (I-V) or trans-impedance CMIA, voltage ...

A PLL-based current-mode PWM circuit suitable for current-mode controlled techniques
2008 9th International Conference on Solid-State and Integrated-Circuit Technology, 2008A wide-range current-mode pulse-width modulation circuit for current-mode controlled techniques is presented in this paper. The proposed circuit has been designed and implemented using 0.35-?m CMOS 2P4M process. The core die size is around 95×115 ?m2 . The experimental results show that the variation of the output frequency within ±0.25%.

A VLSI current mode synapse chip
1995Two-quadrant multipliers are required for several neural network architectures. The efficient implementation of these architectures in silicon requires the development of small, compact, reliable and accurate hardware multipliers. This paper details simulation and hardware results for the DYnamic Mirror PuLsed Experimental Synapse (DYMPLES) Chip ...

A current-mode exponential amplifier
IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 2000The authors present an analog circuit architecture that implements the function f(x, y)=x/spl middot/e/sup a/spl middot/y/, where f(/spl middot/,/spl middot/),x and y are expressed by currents. An important property of this circuit is that x and y may either be positive or negative.
