Abstract

This paper presents an ultra-wideband silicon-based amplifier designed to overcome the limitations of traditional transformer-based and distributed amplifier designs. The pro-posed amplifier is implemented in a 0.18 μm SiGe BiCMOS process and operates over a frequency range of 4.5–37 GHz. It features a single-stage differential topology using a common-emitter/common-base (CE-CB) configuration, with a series RC network for negative feedback. An asymmetric differential T-coil structure is employed for broadband input and output matching. Simulation results show return losses better than −10 dB across the full frequency range. The amplifier achieves a peak small-signal gain of 10.2 dB, with gain flatness of ±0.9 dB. It consumes less than 10 mW of DC power and delivers an OP1dB between 6 and 12.7 dBm. The core occupies only 0.14 mm², making it suitable for compact and low-power broadband systems.

基于0.18 μm SiGe BiCMOS技术的非对称t圈匹配网络4.5-37 GHz超宽带放大器

本文提出了一种基于硅的超宽带放大器，克服了传统的基于变压器和分布式放大器设计的局限性。该放大器采用0.18 μm SiGe BiCMOS工艺，工作频率范围为4.5-37 GHz。它采用单级差分拓扑结构，采用共发射极/共基极（CE-CB）配置，采用串联RC网络进行负反馈。采用非对称差分t型线圈结构实现宽带输入输出匹配。仿真结果表明，在整个频率范围内，回波损耗优于- 10 dB。放大器的峰值小信号增益为10.2 dB，增益平坦度为±0.9 dB。它消耗的直流功率小于10mw，输出的OP1dB在6到12.7 dBm之间。核心仅占地0.14平方毫米，使其适用于紧凑和低功耗宽带系统。
