摘要：
A new design for low-voltage CMOS current feedback amplifiers (CFAs) is introduced. This unconventionally implemented CFA exhibits near gain independent bandwidth. An important feature of the design is that the input resistance looking into the X terminal of the current conveyor is reduced by using an extra opamp. This new architecture results in an amplifier whose bandwidth is potentially constant unlike that of conventional design. Complete analysis and simulation results confirm the design topology.
