Cadence virtuoso-based design and analysis of high-speed BiCMOS amplifiers

High-speed BiCMOS amplifiers play a critical role in modern RF, analog, and mixed-signal applications due to their superior performance in terms of gain, bandwidth, and noise characteristics. This paper presents a systematic design and analysis of high-speed BiCMOS amplifiers using the Cadence Virtuoso platform. The study focuses on optimizing performance metrics such as gain-bandwidth trade-off, noise figure, and power efficiency while addressing layout-dependent effects and process variations. Simulations are performed using Cadence Spectre, and results are validated with industry-standard benchmarks. The study highlights significant performance improvements over conventional CMOS and BJT-based designs. A comparative analysis with existing literature is also provided, showcasing the advantages and limitations of the proposed design.
