Abstract

An inverter-based low-voltage current feedback amplifier (CFA) is proposed in the paper. The proposed current conveyor is based on an inverter-based low-voltage second-generation current conveyor (CCII) and an inverter-based buffer. There are no on-chip capacitors in the proposed current conveyor, and it can be designed with standard CMOS digital processes, hence will reduce the cost of chip fabrication. Moreover, the architecture of the proposed circuit without cascoded MOSFET transistors is easily designed and suitable for low-voltage operation. The CFA can be operated in a very low supply voltage such as ±0.6V. The proposed CFA has been simulated with TSMC 0.18μm CMOS processes and validated by CFA based inverting amplifier and non-inverting amplifier.
