Abstract

A differential wideband low-noise amplifier (LNA) based on the current amplification scheme is presented for digital TV tuners. In order to highly improve the linearity and exploit the noise cancellation, a common-gate stage with positive current feedback is integrated in parallel with a common-source stage using the current mirror amplifier. The proposed 0.18-μm CMOS LNA exhibits a power gain of 20.5 dB, an IIP3 of 2.7 dBm, an IIP2 of 43 dBm, and an average noise figure of 3.3 dB with 32.4 mW power consumption at a 1.8-V power supply and 0.12 mm² area.
