Performance Analysis of Operational Amplifier for High Gain & Low Power Applications

In this paper diverse technologies are utilized to improve the performance of operational amplifier, these parameters are basic piece of all the analog and mixed circuits. Major performance parameters of analog circuits are DC gain, Slew rate, UGBW, Power consumption, Area and settling time. In past designer's primary concern was to enhance gain and diminish size of gadget, although in modern era low power and low voltage are recent research area of designers. Positive feedback is exceptionally popular and it plays critical job for amplification. Review introduces a graphical method to make relative examination of various techniques on premise of year to year variation and talk about how these parameters get improved from last one to two decades. Here a comparative survey is introduced to make it clear what's recent trends are going on for better performance of analog and mixed circuit.
