N2 - A high performance highly integrated sub-GHz wideband differential low-noise amplifier (LNA) for terrestrial and cable digital TV tuner applications is realized in 0.18 μm CMOS technology. A noise-canceling topology using a feed-forward current reuse common-source stage is presented to obtain low noise characteristics and high gain while achieving good wideband input matching within 48-860 MHz. In addition, linearization methods are appropriately utilized to improve the linearity. The implemented LNA achieves a power gain of 20.9 dB, a minimum noise figure of 2.8 dB, and an OIP3 of 24.2 dBm. The chip consumes 32 mA of current at 1.8 V power supply and the core die size is 0.21 mm2.
