چکیده
CMOS continuous-time and switched-capacitor filters which operate at high frequencies with high Quality factor Q are difficult to realize. The finite gain and tlie fulite bandwidth of the integrator amplifiers are the main limitation. This paper describes two techniques to siniultaneously increase bandwidth. transconductance. and DC-gain of an amplifier without changing the excess bias or the power dissipation. Implementations of a continuous-time band-pass filter to demonstrate the liigli frequency capabilities of the proposed architectures are described.

Gain and bandwidth boosting techniques for high-speed operational amplifiers
CMOS continuous-time and switched-capacitor filters which operate at high frequencies with high Quality factor Q are difficult to realize. The finite gain and the finite bandwidth of the integrator amplifiers are the main limitation. This paper describes two techniques to simultaneously increase bandwidth, transconductance, and DC-gain of an amplifier without changing the excess bias or the pow...

In this paper a new high gain bandwidth (GBW) and low power folded cascade OPAMP is presented. It has been implemented and layouted by CADENCE software in 0.18μm. Its DC gain is 82db and its bandwidth is 200MHz. Power consumption is one of the main design challenges in very-lowvoltage high-speed analog integrated circuits. In this paper, different techniques to reduce the power consumption in l...
متن کاملA Novel Design for a Current Feedback Amplifier
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 ...
متن کاملHigh bandwidth low power operational amplifier design and compensation techniques
The need for high bandwidth operational amplifiers (op amp) exists for numerous applications. This need requires research in the area of op amp bandwidth extension. The exploited method in this thesis uses a class of compensation called Indirect Feedback Frequency Compensation in which the compensation current is fed back indirectly from the output to an internal high impedance node, to extend ...
متن کاملActive-Feedback Frequency-Compensation Technique for Low-Power Multistage Amplifiers
An active-feedback frequency-compensation (AFFC) technique for low-power operational amplifiers is presented in this paper. With an active-feedback mechanism, a high-speed block separates the low-frequency high-gain path and high-frequency signal path such that high gain and wide bandwidth can be achieved simultaneously in the AFFC amplifier. The gain stage in the active-feedback network also r...
