Abstract

A CMOS LNA supporting multiple mobile video standards (MediaFLO, DVB-H, and ISDB-T) is implemented using a 0.18 μ CMOS process. The LNA uses a novel feedback configuration and implements an RF elliptic low-pass filter (LPF) response. Because of this elliptic LPF response, the receiver is able to operate concurrently with radio transmitter leakage from GSM, DCS, WLAN, and Bluetooth. The design decouples the feedback path from the main path to allow integration of the LPF as well as obtain wideband input matching. Measurement results show voltage gain of 25 dB, NF of 1.6 dB, and IIP3 of-1 dBm in MediaFLO mode. DVB-H mode demonstrates voltage gain of 25 dB, NF of 1.8 dB, and IIP3 of-1 dBm while achieving interference rejection greater than 70 dB.
