A differential lower noise amplifier (LNA) for wireless local network (WLAN) in front-end receiver is presented
which is fabricated with a JAZZ 0.35 m 1P4M SiGe BiCMOS process. It can not only reject the common-mode noise signal in input port and but also depress circuit noise for using cascade topology
and realize its high performance. The LNA provides effectively a 50 Ωinput impedance matching and good temperature characteristic. At 2.5 GHz
the LNA exhibits a maximum small signal voltage gain of 29.1 dB
noise figure of 1.3 dB
input/output return loss better than -11 dB
and input IIP3 of -0.24 dBm
respectively. The LNA consumes 3.7 mA from a 3.0V DC supply. The simulation results show that
in comparison with the other LNAs
this LNA has higher voltage gain
lower noise and more efficaciously be utilized in WLAN and related fields.
