Abstract :
This paper presents a design of 1.0 V thermal noise-canceling amplifier using 0.13 mum CMOS technology. The amplifier consists of a CMOS inverter-based transimpedance amplifier, and a noise-canceling circuitry. The thermal noise-canceling circuitry is very simple, and consists of only two CMOS inverters. The simulation result shows the input referred noise of the proposed amplifier is 3 nV/radicHz, which is 21 percent less than that of the transimpedance amplifier. The bandwidth of the circuit (omega-3dB) is 1 GHz, and the power dissipation is 163 muW.
