An Inductorless CMOS LNA with Single input and Differential output

摘要：

This paper presents a design technique of an inductorless CMOS LNA with single-ended input and differential output. Its main amplifier circuit exploits a non-inverting cascode common gate path and an inverting cascode common source path to realize the balun function. No inductor is used in the input impendence match. The noise contribution of components is represented by equivalent current and voltage sources and analyzed for minimization methods. The proposed LNA is processed in a RF 0.18μm CMOS process. With the proposed techniques, the LNA features NF 2.88dB, S11 -20.1dB, voltage gain 21.1dB, P1dB -12.9dBm at 1.575GHz.
