Abstract :
Summary form only given, as follows. We report here a 3-stage shunt-feedback configured operational amplifier using simple-Miller compensation demonstrating 19.2 dB mid-band S21 gain, Pdc = 1020 mW. At 2GHz operation the amplifier shows 54.1 dBm OIP3 and a record high OIP3/Pdc ratio equal to 252. The loop bandwidth is 30 GHz, 5.5 dB NF, and is unconditionally stable from DC-8.5 GHz. The slope-3 breakpoint is at Pout=16.6 mW/tone. The OIP3/Pdc ratio increases represent a 1.7x improvement in the state of the art.
