摘要

在这封信中，提出了一种新的过推方法，以提高具有嵌入网络和有损匹配网络（MN）的放大器在接近-$f_{\mathrm{max}}$频率下的功率增益。增益平面方法已被用于研究当将有损MN添加到嵌入式核心时最大可用增益的变化。所提出的过推方法可以通过将有损MN的影响补偿到嵌入式内核的最大可用增益来有效地提高功率增益。为了验证所提出的方法，在65nm CMOS工艺中实现了一个三级放大器，在134GHz下测得的功率增益为17.1dB。

A Novel Over-Push Gain-Boosting Technique for Embedded Amplifier at Near-fmax Frequencies

In this letter, a novel over-push method is proposed to improve the power gain of amplifiers with an embedding network and a lossy matching network (MN) at near- $f_{\mathrm {max}}$ frequency. The gain-plane approach has been employed to study the change of the maximum available gain when adding the lossy MN to the embedded core. The proposed over-push method can effectively improve the power gain by compensating the effect of the lossy MN to the maximum available gain of an embedded core. To verify the proposed method, a three-stage amplifier has been implemented in a 65-nm CMOS process with a measured power gain of 17.1 dB at 134 GHz.

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
