In this technology era, our life is inseparable from a variety of high tech electronic devices, especially for display applications such as smart phones and tablets. There are integrated with different types of amplifier. In order to enhance the area and power efficiencies, single-stage amplifiers are a prospective replacement of their multi-stage equivalents. This report describes a nested current mirror (NCM) technique for a single-stage amplifier. Specifically, NCM is customizable for different mirror steps, and sub mirror ratios, to balance the performance metrics and capacitive load (C_L ) drivability. The purpose of this project is to design a NCM amplifier to achieve solid enhancements of DC gain, gain-bandwidth product (GBW) and slew rate (SR). The design helps manufacturers to cut down their cost but in order to the performance of NCM amplifier is better than DP amplifier, so their products have better performance.
