Title
A 430nW 64nV/vHz current-reuse telescopic amplifier for neural recording applications
Abstract
This paper presents a low-power low-noise amplifier for neural recording applications. A single-stage current-reuse telescopic topology is proposed to achieve high DC gain and improve the noise efficiency factor (NEF) while allowing the amplifier to be scaled for high bandwidth sensing applications and/or to achieve lower thermal noise floor. The design is fabricated in a standard 0.18μm CMOS process and occupies an active area of 0.16mm2. Experimental measurements show a 430nW power consumption from a 1.2V supply, a thermal noise floor of 63.8nV/√Hz and a corresponding NEF of 1.5.
