Title: A dual positive feedback three-stage low noise amplifier
Abstract: A three-stage low noise amplifier (LNA) using dual positive feedback is presented in this paper. In order to increase voltage gain and forward gain, two positive feedbacks are employed in the LNA circuit. Moreover, the LNA transistors operate at a moderate inversion region, so it is suitable to use in an ultra-low voltage receiver. The proposed LNA is simulated in 0.13μm CMOS technology. The results show that the LNA achieves a minimum noise figure of 3.28dB, a 28dB voltage gain, and a 15.8dB forward gain at 7.1GHz. The LNA consumes 0.92mW from a 0.5V power supply.
