- Abstract
Cascaded Single-Stage Distributed Amplifiers (CSSDAs) are instrumental in achieving ultra-wideband amplification for microwave applications due to their significant gainbandwidth products. However, their functionality is often compromised by internal noise, which detrimentally impacts the linearity of the response. An innovative solution to this prevalent issue is presented in this study through the introduction of the Quasi- Differential Distributed Amplifier (QDDA). Implementing the 0.18μm Complementary Metal Oxide Semiconductor (CMOS) technology, a QDDA with a single-stage fourcascade configuration was designed, fabricated, and tested. The empirical results revealed a high gain of 20dB and an extensive bandwidth of 30GHz. Moreover, the noise figure was observed to be 4.809 with a compact chip size of 0.74mm². This design and the resulting findings were accomplished using the Advanced Design System (ADS) RF simulator. The circuit layout and specifications were subsequently generated using the Cadence tool. This research demonstrates the potential of the QDDA to significantly enhance the performance of CSSDAs, contributing to the advancement of ultra-wideband microwave applications.
