Abstract
Provided herein are apparatus and methods for a cascode amplifier topology for millimeter-wave power application. The cascode amplifier can use a neutralized common source stage cascoded with a bootstrapped common gate stage to provide an amplifier topology having enhanced performance, gain, stability and reliability. Additionally, a bootstrap capacitor of the common gate stage can be patterned between the source fingers and the drain fingers of a cascode transistor so as to improve device performance. Operating as an RF power amplifier, a single-stage cascode amplifier using the neutralized common source stage with the bootstrapped common gate stage can provide greater than 15 dB of power gain to signals of the E band.
