A CMOS Thermal Noise-Canceling Transimpedance-Based Amplifier

摘要

This paper presents a design of 1.2 V thermal noise-canceling differential amplifier using 0.13 um CMOS technology. The circuit is designed based on a CMOS inverter-based transimpedance amplifier. Differential structure with tail current is employed to perform noise canceling of the input transistors. The simulation result shows noise figure (NF) of 2.3 dB. The gain and bandwidth of the amplifier are 42 dB and 2 GHz, respectively. The power dissipation is 13 mW.
