ABSTRACT:
An ultra wideband low noise amplifier (UWB LNA) and amplification method thereof, providing a substantially achieved bandwidth extension by pole-zero cancellation and utilized to transform input impedance matching up to 50 ohm for gaining low noise figure. The ultra-wideband low noise amplifier is composed of a capacitive-feedback amplifier, a resistive-feedback amplifier, an inductive-feedback amplifier, and a buffer amplifier.
