Abstract :
The effect of temperature variations on a cascode low-noise MOS amplifier is analyzed. A gate biasing scheme for temperature compensation is illustrated. RF circuit simulation results show that the low-noise amplifier with temperature compensation can reduce temperature variation effect on the noise figure of the amplifier over a wide range of temperatures. Analytical equations to predict temperature compensation effect are also presented.
