Current Feedback Amplifiers (CFA) are discussed in this report. Current Feedback Amplifiers employ the current mode of signal processing to achieve higher gain-bandwidth product and greater slew rates than those of a Voltage Feedback Amplifier (VFA). The Current Feedback Amplifier topology has an inherent advantage over that of the the Voltage Feedback Amplifier, wherein the amplifier gain can ...

Industry is continuously researching techniques to reduce power requirements, while increasing speed, to meet the demands of today’s low (battery) powered wireless systems. The operational transconductance amplifier (OTA) is a fundamental building block in analog (mixedsignal) design and its performance characteristics are the foundation of system level characteristics. Improving the performanc...

The rapid growth of the hybrid electric vehicles (HEVs) has been driving the demand of high temperature automotive electronics target for the engine compartment, power train, and brakes where the ambient temperature normally exceeds 150°C. An operational transconductance amplifier (OTA) is an essential building block of various analog circuits such as data converters, instrumentation systems, l...

In this paper, we propose the idea of using transimpedance amplifiers, in lieu operational amplifiers (OAs) or transconductance (OTAs) to design capacitively coupled AC amplifiers. The is demonstrated with a current feedback amplifier (CFOA) as an active element, which actually architecture consisting voltage buffers and copiers (mirrors). This last characteristic further exploited make corner ...

The comparator is designed in pipelined ADC. FINFET is the technology which performs the dual gate MOSFET. This thesis focuses on the high-speed design of pipelined ADC. In the meanwhile, we try to minimize the power dissipation as well. In this thesis, A semidigital Gm-based amplifier is proposed for a low-power pipelined analog-to-digital converter (ADC )in HSPICE .And also we compare the pow...

This paper describes an instrumentation amplifier (INA) with three operational amplifier (op amp) topology, for biomedical applications. To achieve low offset new circuit technique is achieved by adding NMOS transistor and two phase clock scheme with a frequency of 20 KHz. With the unity gain bandwidth of 92 KHz , the open loop gain of this instrumentation amplifier is found to be 50 dB and hav...
