Abstract

The design of bio-medical signal acquisition system has become possible because of advancements in CMOS technology at rapid rate with tradeoffs in area, speed and power. These advancements have made it easy to continuously monitor and process the various bio-physiological signals whose amplitude and frequency characteristics are in the voltage range of few µV to mV and a frequency range of dc-10 kHz respectively. In bio-medical signal acquisition system, the first and the foremost important block is front-end amplifier (FEA), also sometimes referred as low noise amplifier (LNA) or preamplifier, or in some applications also called as instrumentation amplifier (IA). The important characteristics of such an analog front end are, it should exhibit low-power, low-noise, high gain, high CMRR, high PSRR, high input impedance, high dynamic range and smaller area. Tradeoffs among these characteristics can be optimized in a FEA design by suitable selection of its topology. Design of such analog front end amplifier has a vital role in defining the performance characteristics of the overall biomedical system. In this research work a novel amplifier designs are proposed to improve the noise efficiency especially for biomedical applications.
