Design of Broadband CMOS Amplifier Using Bandwidth-Compensation Technique

A novel architecture is proposed to design broadband CMOS amplifier in this work. The proposed architecture includes the two-stage cascade and shunt peaking techniques. Accordingly, the bandwidth-compensation is executed to achieve gain flatness, broadband, low noise, and low power performances. The low noise amplifier (LNA) was fabricated in TSMC 0.18-mum CMOS process. Measurement results show that the design circuit accomplishes the highest gain-bandwidth product, which has the value of 173 GHz, compared with reported works using a 0.18-mum CMOS technology.
