IEEE International Symposium on Circuits and Systems, 2003
Traditional voltage-feedback amplifier configurations, both discrete and integrated, have always suffered from the severe disadvantage of drastically restricted bandwidth at high gains due to the problem of constant gain-bandwidth product. The author shows how adopting a current-mode approach to a range of amplifier designs based on current conveyors ...

Current mode ternary D/A converter
Proceedings Eleventh International Conference on VLSI Design, 2002In this paper current mirror sources have been employed to design a ternary D/A converter. A much better performance and area saving over the 3R-4R resistive network has been achieved.

Voltage-mode filters and especially their linearity and dynamic range suffer from the low supply voltages of deep-sub-micron and nanometer CMOS. This fact served as motivation to investigate current-mode filters with the hope for a better linearity and larger dynamic range. Current-mode filters also may allow saving of current-to-voltage and voltage-to-

Osteoporosis: Current Modes of Prevention and Treatment
Journal of the American Academy of Orthopaedic Surgeons, 1999The most common metabolic bone disorder is osteoporosis, which affects 25 million Americans, of whom 80% are women. Bone loss in women occurs most commonly after menopause, when the rate of loss may be as high as 2% per year. Bone mass can be determined with dual-energy x-ray absorptiometry.

Abstract With the arrival of monolithic processes for the fabrication of bipolar transistors during the mid-1960s, it seemed like a good time to examine new paradigms for design. Current-mode (CM) was attractive because it suggested that small voltages swings could be used to process analog signals represented as currents; whatever voltages that did ...

Current-mode threshold logic gates
Proceedings 2000 International Conference on Computer Design, 2002In this paper, we present low-power and high-performance logic gates called the current-mode threshold logic (CMTL) gates. Low-power dissipation is achieved by limiting the voltage swing on the interconnects and the internal nodes of the CMTL gates. High-performance is achieved by the use of transistor configurations that sense a small difference in ...

Linear current-mode ISFET arrays
2016 IEEE International Symposium on Circuits and Systems (ISCAS), 2016This paper investigates ISFET circuits operating in current mode and demonstrates linear pH-to-current operation. The two operating regions that provide linear gate-voltage to drain-current operation are the triode and velocity saturation regions which have been compared with a focus on pH sensing applications. Subsequently, two sensor arrays optimised

A current-mode neuro-fuzzy network
1998 IEEE International Conference on Electronics, Circuits and Systems. Surfing the Waves of Science and Technology (Cat. No.98EX196), 2002A new neuro-fuzzy network based on a neural model called Approximate Identity Neural Network (AINN) is presented in this work. The ability of neural networks to learn from examples and the ability of the fuzzy model to code human knowledge can be helpfully joined to create an adaptive fuzzy system.

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

New current-mode precision rectifiers
1993 IEEE International Symposium on Circuits and Systems, 2002Current-mode techniques are used to realize improved high-frequency precision full-wave rectifiers (PFWRs). Three alternative topologies are described and compared in performance with the classical operational amplifier (op-amp)/diode PFWR. These are a new op-amp supply current-sensing PFWR, a modified classical op-amp/diode design and a novel current ...
