Wideband Low Noise Unity Gain amplifier using linearity enhancement technique

Abstract

A low noise-figure (NF) and Unity power gain 1-100 GHz ultra-wideband Low Noise π Network with excellent linearity is reported. An π-match input network, Capacitive feedback with series and shunt inductive peaking techniques are used to achieve wideband impedance matching with low noise figure as well as flat unity gain response. This technique exists unity voltage and current gain so that matching used as a follower. The LNA consumes power dissipation 1.586 mW, and group-delay (GD) variation less than 0.1f ps in the frequency range 1-100 GHz. Furthermore, the LNA achieves minimum NF of 0.4 dB for frequencies 1-100 GHz, one of the best NF results reported for frequencies 1-100 GHz. CMOS ultra-wideband Low Noise π Network. Low power consumption network is versatile demanded in modern technology, modern technology want such type of amplifier which gives low power consumption with less reflection, In this paper presented technique to reduce leakage power consumption with small value of reflection. Here design low power dissipation network using compensation and feedback technique.
