Several possible implementations of variable-gain current conveyors are proposed. They can be designed with two opamps and current mirrors and exhibit constant bandwidth property. Their configuration as differential-output current amplifiers is straightforward.
This chapter aims to introduce optical receivers in general and application of electronic circuits in these receivers then some important parts of these electronic circuits which are the amplifiers are discussed. An attempt has been made in this chapter to provide some useful information about different aspects of the optical communication in our life and the importance of high speed wideband a...
This paper analyses a method by which chaos is generated using electronic circuits. The chaos generator required for this purpose is based on utilizing the one dimensional piece wise linear Bernoulli Shift map. The iterative map is realized using a feedback system consisting of programmable amplifier and a unity-gain sample-and-hold amplifier. The sample and hold amplifier provides necessary de...
DESIGN AND IMPLEMENTATION OF A FOUR TERMINAL FLOATING AMPLIFIER AND ITS APPLICATION IN ANALOG ELECTRONICS By José A. García Rivera The field of analog electronics has developed and matured for the past two decades. Within this field, design of analog amplifiers has received attention due to changes in technology. Amplifier circuits, considered analog devices, are found anywhere in many house el...
The main building block of analog electronics is a voltage amplifier: an electronic device capable of amplifying small alternating current (AC) voltage signals. Many graphene analog electronic devices, performing different functions, 1-5 have recently been proposed stemming from high carrier mobility 6,7 and ambipolar transport in graphene field effect transistors (FETs). However, none of these...
It is accepted that the electromagnetic interference should be addressed with statistical analysis. Usually the impact of electromagnetic interference on different electronic samples is evaluated and the average immunity level is used as a reference. However, this method does not provide enough information to know the probability of failure to the electromagnetic interferences of an electronic ...
We present a review on the electronic design of chaotic oscillators. Multi-scroll chaotic oscillators are listed according to their electronic implementations. A 3-scrolls oscillator is analyzed from its mathematical description, and designed with current-feedback operational amplifiers. Finally, we list the integrated realizations, and discuss key points for future research on the design of mu...
Chirped quasi-phase-matched optical parametric amplifiers (chirped QPM OPAs) are investigated experimentally. The measured collinear gain is constant over a broad bandwidth, which makes these devices attractive candidates for use in femtosecond amplifier systems. The experiment also shows that chirped QPM OPAs support noncollinear gain-guided modes. These modes can dominate the desired collinea...
We describe our progress on the development of extended interaction klystron amplifiers operating at 670 GHz, meeting demanding requirements for output power, gain, bandwidth, and efficiency.
