38-42ghz CMOS Power Amplifier With Matched Co-Planar Strip Line
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
In this work, design of CMOS power amplifier (PA) with matched co-planar line for millimeter wave applications is proposed. This new design of CMOS power amplifier achieves high output power and power added efficiency with good matching. A 50Ω co-planar transmission line as a matching network is adopted in class AB PA for enhancement of efficiency. The circuit is simulated using 65nm TSMC CMOS technology in ADS tool. As shown by the simulation results: at 38-42 GHz under 1.5 V power supply, the output power is 19dBm while input power signal is 0dBm, the power gains more than 20dB of broadband within 38.5GHz to 41.8GHz, and the power added efficiency（PAE）is 74%.
