Abstract
This paper presents a low noise amplifier (LNA) employing a noise cancellion technique for WiMAX applications. The design of LNA is based on the input impedance matching with noise cancellation in 0.35-µm standard SiGe BiCMOS process. The chip size is equal to 0.84 mm × 0.18 mm. The crucial simulated results include that the noise figure (NF) is below 2.1 dB in the frequency range of 2 GHz to 3 GHz, the gain is equal to 13.3 dB at 2.6 GHz, the input 1 dB compression point (IP1dB) is -11 dBm, and the input-referred third-order intercept point (IIP3) is 2.5 dBm. The power consumption is 13.2 mW from the supply voltage of 1.8 V. The NF is improved by 0.73 dB using a noise cancellation technique.
