A new Current Feedback Amplifier (CFA) suitable for VLSI applications is presented in two different designs to serve both low power (LBW design) and high bandwidth (HBW) applications. The new circuit is employing positive current conveyor followed by amplifier followed by buffer to achieve vey high trans-impedance for this CFA circuit without needing to stack many transistors together and at the same time to use the whole bandwidth range. The proposed circuit is designed and simulated using 90nm technology kit in cadence. The bandwidth of the LBW circuit is approximately constant at 32MHz and for HBW is around 107MHz.
