Abstract :
In recent years, with the development of Wireless Body Area Network (WBAN), it has become the key technology which can be used in many medical and non-medical applications. The design of a low noise amplifier which is applied to the body-channel communication (BCC) is presented in this paper. It adopts TSMC RF CMOS 0.18μm process. Parallel resistor´s negative feedback structure and noise cancellation technology are respectively used for matching impedance and reducing circuit noise. Simulation results show that in 80-120Mhz BCC working frequency band, the circuit has a gain of 12dB, the noise figure is less than 3.5dB and the IIP3 is 1.4dBm, which all meet the design requirements.
