A novel current-mode active-only single-input and three-output (SITO) universal filter using three plustype second-generation current-controlled conveyors (CCCIIs), one operational transconductance amplifier (OTA) and two operational amplifiers (OAs) is presented. The circuit is fully programmable and implements simultaneously lowpass (LP), bandpass (BP),and highpass (HP) functions while Notch ...

A novel current-mode active-only single-input and four-output (SIFO) universal filter using four plus-type second-generation current-controlled conveyors (CCCIIs), one operational transconductance amplifier (OTA) and two operational amplifiers (OAs) is presented. The circuit is fully programmable and implements simultaneously lowpass (LP), bandpass (BP), highpass (HP) and Notch (BS) functions w...

The history of Tow–Thomas second-order filter is reviewed. Two alternative generation methods of the Tow–Thomas filter are discussed. The first is a generation method from the second-order passive RLC filter and the second is from the multiple feedbacks inverting low-pass filter using a single op amp. Several forms of the circuit are briefly reviewed. Passive and active compensation methods to ...

This paper presents the design of CMOS operational transconductance amplifiers (OTAs) with very small transconductance (of order of nano ampere per volt), which uses in very low frequency continuous time filters. This design uses current division technique to reduce the transconductance of OTA. This design is simulated in SPICE tool using 0.25μm technology model file.

On the morning of September 11, 2001, the United States and the Western world entered into a new era – one in which large scale terrorist acts are to be expected. The impacts of the new era will challenge supply chain managers to adjust relations with suppliers and customers, contend with transportation difficulties and amend inventory management strategies. This paper looks at the twin corpora...

Abstract: This paper presents the design methods for the designing and simulation of implication function (mamdani) using two stage CMOS operational amplifier in SPICE. This paper also presents how the first three steps of fuzzy system i.e. fuzzification, rule composition and implication process are merged and get the output for each rule. I have also calculated the electrical parameters like s...

-Generally good agreement was obtained between the single-event output voltage transient waveforms obtained by exposing individual circuit elements of a bipolar comparator and operational amplifier to an ion microbeam, a pulsed laser beam, and circuit simulations using SPICE. The agreement was achieved by adjusting the amounts of charge deposited by the laser or injected in the SPICE simulation...

For the analog circuit designer, there can be no better fate for simulations, viewing this situation in terms of which model to use. Designers no longer need worry about whether the third party supplier’s model can really cut it. Speaking in terms of the ultimate potential, no one can know an actual part better than the people who designed and produced it, that is the original source IC vendor....
