In real world signal processing systems, the operational amplifier is the main block for detecting the analog signal. This paper presents a multi optimization technique for the optimal sizing of Transconduc amplifier. By using multiCMOS folded cascode operational transconductance amplifier that operates at low voltage is designed for signal processing application. The MOGWO is a swarm intellige...

Current mirrors are core structures for almost all analog mode circuits and are integral part of a signal processing elements like op amps. The performance of analog structures largely depends on their characteristics. In this paper we present some of the current mirror circuits and analyze their performances, so that one can choose a suitable current mirror for a particular application.

In the measurement of dc current for the range of 10-6-10-‘2 A, a stable electrometer is required. The electrometer circuit is usually implemented by simply probing the voltage drop on a load resistor using a sensitive voltage amplifier.’ In this scheme, different values of the load resistor are needed to cover multi decade range without saturating the voltage amplifier. This results in differe...

INTRODUCTION: In our previous work on passive current source RF power amplifiers, it was noted that additional inter-element isolation in a parallel transmit coil array was possible when the lengths of the coaxial cables that connected the amplifiers to the coils were reduced [1,2]. In addition, shorter cable lengths also lead to reduced power loss and cost. This can be achieved by placing the ...

Abstract This report is an outcome of a master degree project at Linköpings University in cooperation with Micronic Laser Systems AB. The purpose with this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver se...

A novel technique for a self-equalized distributed amplifier is presented by showing the analogy between transversal filters and distributed amplifier topologies. The appropriate delay and gain coefficients of amplifier circuit are obtained by a Fourier expansion of the raised cosine spectrum in the frequency range of 0-40GHz.

High-power high-voltage dc power supply has been developed based on series resonant converter technology for a MW class RF amplifier. For low-voltage ripple, an IGBT inverter consisting of 1400 V-600 A devices is drives with a maximum switching frequency of 31.2 kHz. A performance test was carried out using an RF amplifier. We examined this power supply under two different conditions. One was w...

This article reviews 2 circuits, which are electronically controllable active-only floating positive and negative inductance simulators. Each floating inductance simulator comprises merely one operational amplifier (OA) and one current conveyer transconductace amplifier (CCTA). The simulated inductance values can be controlled electronically by adjusting bias current of the CCTA. The circuit pe...

In this paper a new method for the design of a linear phase distributed amplifier in 180nm CMOS technology is presented. The method is based on analogy between transversal filters and distributed amplifiers topologies. In the proposed method the linearity of the phase at frequency range of 0-50 GHz is obtained by using proper weighting factors for each gain stage in cascaded amplifier topology....
