Design of Low-Voltage High Performance CMOS-Current Feedback Amplifier Using Indirect Feedback Compensated Op-Amp

摘要：

In this paper low-voltage high performance CMOS Current Feedback Amplifier is designed using indirect feedback compensated operational amplifier and the results are compared with the existing topology. The Operational Amplifier used has the open loop gain of 101.8 dB with 25ns settling time,unity gain bandwidth 169.8 MHz,phase margin 70°with rail to rail output swing. The CMOS-Current Feedback Amplifier designed using this Operational-Amplifier has nearly gain independent bandwidth with settling time observed as 44 ns and slew rate increment up to 20V/μs. The circuit is designed at 0.18μm Digital CMOS process with supply voltage 1.8 volt.
