摘要

The objective of this paper is to design a Low-Voltage, Low-Power and High-Gain Operational Amplifier used for Data Conversion process. These Data Converters are used in Biomedical and Telecommunication applications. This work presents the optimized architecture of an operational amplifier, The characteristics are verified by using 0.18μm CMOS technology and also outlines the performance of an op-amp at supply voltage 1.2V. The simulation results show that the Open Loop Gain≥79dB, Unity Gain Frequency≥110MHz, Slew Rate=175v/μs, CMRR≥89dB, PSRR≥75dB, ICMR=0 to 1.2v(Rail to Rail), Settling Time≤10ns, Output Swing= close to rail and Input Offset Voltage=0.001μv
