Abstract:
In high performance analog circuit, it is a very challenging task to design a high performance
complemtary metal oxide semi-conductor, which is used in either ADC or DAC. As we are
dealing with high performance circuit, to meet these requirement both accuracy and fast settling
of system is needed, OP-Amp with high DC gain frequency can satisfy both of these
requirement. Although a Op-amp with high DC gain satisfy these requirement, but still in many
aspects which leads to complementary demands, as the intrinsic gain of many devices are
limited.
OTA is an Op-amp without an output driver. It is capable of driving small capacitive load. These
makes OTA a well suitable for pipeline application.The whole procedure is focused on the
development of ultra low power amplifier requiring low silicon area but been able to drive high
capacitive load.
