A CMOS ultra-wideband LNA utilizing a frequency-controlled feedback technique
A 3.1-10.6 GHz, single-stage, low noise amplifier employing a frequency dependant feedback network is reported. The amplifier was implemented in a 0.18 /spl mu/m CMOS process, and attains a gain of 8 dB, input matching of -13 dB, and a minimum spot noise figure of 3.5 dB (4.4 dB average). The amplifier exploits a combination of negative and positive feedback to attain a flat gain across the entire bandwidth with an input-referred 1 dB compression at -2.48 dBm. An ultrawideband noise and power matching technique utilizing frequency dependent Miller multiplication factors is presented. This is believed to be the first application of this technique within an ultrawideband low noise amplifier.
