A Novel Low Voltage, Low Power and High Gain Operational Amplifier Using Negative Resistance and Self Cascode Transistors
In this work a low power, low voltage and high gain operational amplifier is proposed. For this purpose a negative resistance structure is used in parallel with output to improve the achievable gain. Because of using self cascode transistors in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain. To evaluate the...
متن کاملWideband Low Distortion, High Gain Operational Amplifier
The OPA643 provides a level of speed and dynamic range previously unattainable in a monolithic op amp. Using a de-compensated voltage feedback architecture with two internal gain stages, the OPA643 achieves exceptionally low harmonic distortion over a wide frequency range. The "classic" differential input provides all the familiar benefits of precision op amps, such as bias current cancellation...
متن کاملA low noise amplifier with improved linearity and high gain
In this paper presents a optimization of linearity of low noise amplifier by using post linearization techniques. in this technique we have used diode connected mosfet as IMD sinker also used interstage matching for gain enhancement and reducing the effect of nonlinearity in common gate stage of cascode amplifier, this has done by using UMC .18um CMOS Technology in cadence tool. We got gain 14d...
متن کاملA 1.2 V Low-Noise-Amplifier with Double Feedback for High Gain and Low Noise Figure
Faculdade de Ciências e Tecnologia Departamento de Engenharia Eletrotécnica e de Computadores Mestrado Integrado em Engenharia Eletrotécnica e de Computadores por David Jorge Tiago Amoêdo In this thesis we present a balun low noise amplifier (LNA) in which the gain is boosted using a double feedback structure. The circuit is based in a Balun LNA with noise and distortion cancellation. The LNA i...
