Abstract
This paper presents a technique for improving noise performance of common-gate (CG) fullydifferential
front-end amplifier. The circuit employs a noise canceling circuitry, which is connected in the
differential configuration with tail current. The thermal noises of input CG transistors can be fully suppressed.
The proposed amplifier is designed using 0.13 μm CMOS technology under 1.5 V supply. Simulation results
show noise figure (NF) of 2.8 dB. The voltage gain and bandwidth of the amplifier are 15.3 dB and 1.75 GHz,
respectively. The power dissipation is 12.3 mW.
