A Nonintuitively Frequency-Staggered Wideband mm-Wave Low-Noise Amplifier
Abstract
An algorithmic topology optimization framework is presented to autonomously synthesize nonintuitive, multilayered wideband mm -Wave LNAs with arbitrary stage count. Cooptimization of actives and passives directly at a layout level enables improved tradeoffs among metrics like gain, bandwidth, NF, and DC power. A 3-stage SiGe HBT LNA prototype fabricated in a 180 nm BiCMOS process achieves 26.3 dB gain,$22-\text{to}-46 \text{GHz} 3 \text{dB}$bandwidth, 3.1 dB NF and 18 mW DC power, experimentally validating the method.
