This paper reports the design of a highly-linear CMOS amplifier for Variable Gain Amplifier (VGA) applications. A better than –60dB 3rd harmonic distortion at differential output level of 1V peak-to-peak is obtained by utilizing a linearization scheme that does not rely on the active devices. The amplifier maintains 3dB bandwidth over 300MHz. A noise figure at 8.6dB is obtained with source impe...

this paper surveys recent research on Low Noise Amplifier (LNA) design for Cognitive Radios (CR). Design challenges and requirements of CR are discussed and recent advances in topologies and design techniques are presented, compared and summarized. The classical trade-offs of linearity, gain, input impedance matching and noise are discussed herein with respect to the Wide Bandwidth requirement....

..4bstract—A novel ultrabroad-band amplifier configuration suitable for GaAs FET’s has been developed. The developed amplifier circuit operates as a capacitor-resistor ( C–R ) coupled mnpfifier circuit in the lowfrequency range in which IS21 I for the GaAs FET’s is constant. It also operates as a lossless impedance matching circuit in the microwave frequency range in which IS21 I for the GaAs F...

Josephson parametric amplifiers are an important part of a modern superconducting quantum computing platform and squeezed states generation devices. Traveling wave impedance-matched provide broad bandwidth for high-fidelity single-shot readout multiple qubit circuits. Here, we present quantum-limited 3-wave-mixing amplifier based on nonlinear asymmetric inductive elements (SNAILs), whose useful...

In this paper, a low-power adaptive low noise amplifier (LNA) is presented. The LNA is based on a bipolar cascode topology, uses inductive source degeneration and emitter area scaling to achieve noise and input-impedance matching simultaneously. The input impedance and the noise factor were simulated as function of the bias collector current and the results show that both are approximately cons...
