Title: Design and Simulation of Operational Amplifier using Non Conventional Method for Low Power Applications
Abstract: The power budget is a very stringent requirement for the portable biomedical instrument. In this paper, the bulk driven(Non-Conventional Method) two-stage operational amplifier designed and simulated for small size and low power biomedical applications. The first stage is a non-tailed differential amplifier with bias current control. The second stage is a common source amplifier with a capacitive load. The pole splitting method is utilized for stability and aspect ratios are calculated using the graphical method(gm/Id). The total power dissipation is 15.77nW for the gain level at a gain of 61dB. The simulation is performed using Cadence Virtuoso in 0.18µm CMOS technology with supply voltage 0.3V.
