A novel noise reduction technique, for an operational transconductance amplifier (OTA), has been proposed. This adds a current steering branch parallel to the differential pair, with a view to reducing the noise contribution by the cascode current sources. Hence, this reduces the overall input-referred noise of the LNA, without adding any additional power. The proposed technique implemented in 65[Formula: see text]nm CMOS technology achieves 30 dB closed-loop voltage gain, 0.05[Formula: see text]Hz lower cut-off frequency and 100 MHz 3-dB bandwidth. It operates at 1.2[Formula: see text]V power supply and draws 1[Formula: see text][Formula: see text]A static current.
