SESSION 29<br />
1:30 PM<br />
A 150GHz 3-stage amplifier in digital 65nm CMOS occupies 0.41mm 2 . Transistor layout is<br />
optimized to yield 4.8dB of maximum stable gain at 150GHz. Dummy-prefilled microstrip<br />
lines are used. Shunt-stub tuning and radial stubs reduce matching loss. Measurement<br />
shows 8.3dB gain, 6.3dBm Psat, 1.5dBm P1dB and 27GHz 3dB BW while consuming<br />
25.5mW at 1.1V.<br />

Two W-band amplifiers are implemented in 65nm CMOS. The slow-wave CPW-based<br />
amplifier achieves +10dBm output power, 7.5dB NF,and 13dB gain at 100GHz with a 72mA<br />
current consumption at 1.2V. Chip size of the implemented slow-wave amplifier is<br />
0.33mm2 . Substrate shielding of the passives improves performance when compared to<br />
the other amplifier which uses unshielded passives.<br />
29.3 A 26dB-Gain 100GHz Si/SiGe Cascaded Constructive-Wave Amplifier<br />

A 0.12μm SiGe BiCMOS 82mW wideband mm-wave amplifier topology, based on<br />
cascaded traveling-wave stages constructively add forward traveling waves while<br />
canceling backward traveling waves. It achieves 26dB gain at 99GHz with a 14GHz 3dB<br />
bandwidth, for overall 290GHz GBW. The input and output return losses are greater than<br />
15dB and 12dB, respectively. The output-referred P1dB is -0.1dBm.<br />
