  A Low Power Variable Gain Amplifier for Biomedical Application

  By dipesh panchal, amisha naik, N M Devshrayee

  Abstract: This paper describes the design and simulation of low power variable gain amplifier used for biomedical application like hearing aid, Electronic Cardiograph and neural recording system. The MOS transistor is designed to operate in subthreshold region for low power application. The gain of amplifier is changed by selecting different values of input capacitor in the frequency range of 20 Hz–20 KHz. The simulated total power dissipation is 3µW. The gain …

  Automatic Gain Control Amplifier for Analog Front End in Biomedical Applications

  By dipesh panchal, Bhumit Rojivadia, Krunal Tank

  Abstract: This paper presents the design review of feed-forward automatic gain control (AGC) amplifier to be used in analog front end of biomedical applications such as hearing aid. To make system low-power, the design of each block is optimized and all elements are realized using MOS. The whole design is simulated in LT spice IV using 0.18 µm CMOS technology and the results are presented. Keywords: Automatic gain control (AGC), biomedical …
