A family of gm −C biquad structures is derived. These biquads require only a pair of grounded capacitors and three transconductors. It is shown that a pair of complex zeros can be realized simply by replicating the output stage of the transconductance block, thereby constructing a second output current that is proportional to the original output current. Although these biquad structures are ver...

the design and application of a fuzzy logic based controller to a leakage current relay waspresented in this paper. a novel approach based on fuzzy logic to form the tripping action of leakagecurrent relay was investigated. in addition to the theoretical aspect of fuzzy logic, detection of a leakagecurrent, measurement of the leakage current, determination of its duration, trip opening of fault...

A high-linearity and high-efficiency MMIC power amplifier is demonstrated adopting a new on-chip adaptive bias circuit, which improves efficiency at the low output power level and linearity at the high output power level automatically. The intelligent two-stage W-CDMA power amplifier using the newly proposed adaptive bias circuit extends the maximum linear output power of 0.6dB and exhibits an ...

Abstract. In this paper, we propose a new category of current-mode Łukasiewicz OR and AND logic neurons and logic networks and show their ultra low power realization. The introduced circuits can operate with very low input signals that set up the operating point of transistors in the subthreshold region. In this region, the mismatch between transistors has much stronger impact on the current mi...

A current mirror (CM) based on self cascode MOSFETs low voltage analog and mixed mode structures has been proposed. The proposed CM has high output impedance and can operate at 0.5 V. P-Spice simulations confirm the high performance of this CM with a bandwidth of 6.0 GHz at input current of 100 μA. Keywords—Current Mirrors, Composite Cascode Structure, Current Source/Sink.

This paper presents a novel CMOS current source suitable for low voltage applications. The new design shows better compliance voltage than the simple two transistor current mirror while offering improved accuracy and output impedance, featuring 140KR output resistance at an output voltage of 30mV and output Current of 30pA. The circuit has been manufactured in a 0.25pm. 2.5V power supply digita...

Multilevel inverters have been developed due to limitations of the conventional two-level voltage source inverters (VSIs). Most of the topologies of multilevel inverters that have been presented in the literature are based on the sharing of the rated voltage between the switches so that the switches with lower voltage ratings can be used. In these topologies, the current rating of all of the sw...
