Özet

This paper presents a common gate low noise amplifier utilizing a passive feedback network that provides a competitive and highly integrated front-end solution for mobile handset devices. This design utilizes a resistive load instead of the inductive one used in other designs to reduce the on-chip silicon area. The design does not need an external matching network which decrease the area of the PCB while achieving a sufficient input impedance matching, S 11 . It achieves a measured gain higher than 20 dB, noise figure less than 3 dB and input referred third order intercept point (IIP3) value higher than − 2.5 dBm at 2.3 GHz. The design is implemented in 65 nm UMC CMOS technology, occupies a total area of 0.065 mm 2 and consumes 5 mW from a 1.4 V supply.
