A novel low-input-resistance, high-output-resistance and wide-bandwidth current mirror using class-AB FVF cell

摘要

A novel low input and high output resistance current mirror using class-AB FVF cell is presented in this paper. In the proposed current mirror, class-AB cascoded FVF cell acts as a current sensing cell and results in low input resistance of the proposed current mirror. The proposed current mirror uses a regulated cascode output stage to enhance its output resistance. The various other advantages offered by the proposed current mirror are large current mirroring range with high accuracy, low THD, and wide bandwidth. The physical layout of the proposed current mirror has been designed in the Cadence tool. The post-layout simulation results have also been demonstrated to validate its performance.
