|Issue Date:||2020||Conference:||35th Conference on Design of Circuits and Integrated Systems - DCIS 2020||Abstract:||A Distributed Power Amplifier (DPA) with a tapered drain line is presented in this paper. The drain line impedance tapering technique allows to obtain a higher output power and efficiency compared to the conventional approach, whereas a constant drain line impedance avoids impedance changes in the power supply drive signal. The design was implemented using the D01GH/Si technology provided by the foundry OMMIC. The DPA achieves a Psat of 32 dBm and a flat gain over 14 dB in a frequency range that ranges from 1 to 8 GHz. Moreover, this circuit achieves a Power Added Efficiency (PAE) of 50%. Finally, the occupied area of the DPA is 2.2x1.2mm2 excluding pads.||URI:||http://hdl.handle.net/10553/77075||ISBN:||9781728191324||DOI:||10.1109/DCIS51330.2020.9268621||Source:||2020 XXXV Conference on Design of Circuits and Integrated Systems (DCIS)|
