Abstract :
A comparison is made between a Silicon Germanium (SiGe) bipolar transistor LNA and a Silicon (Si) Complementary Metal Oxide Semiconductor (CMOS) transistor Low Noise Amplifier (LNA), both operating at 2.1 GHz, a typical application being a Universal Mobile Telecommunications System (UMTS) cellular mobile phone. The designs are based on a simple common source (CS) amplifier design, and matched with a combine shunt feedback and resonance matching techniques. The SiGe bipolar design achieves better gain and NF, with significantly lower current consumption.
