Abstract :
In this paper, we design a low power, low noise transimpedance amplifier for ultra-low biosignal amplification. The proposed transimpedance amplifier is implemented in a standard 6 metal, 1 poly 0.18μm CMOS process. The amplifier is capable of producing 215MΩ transimpedance gain, 0.615MHz bandwidth; 910fA/√Hz input referred noise at 100Hz while consuming only 139μW DC power.
