| 摘要 |
A noise shaped differential amplifier having a reduced common mode signal in accordance with an embodiment of the invention is described. In the described embodiment, the noise shaped differential amplifier includes a noise shaper having a common mode signal controlled by an attenuation operational amplifier that is coupled to a voltage divider circuit and a sense resistor divider. In this arrangement, the attenuation operational amplifier controls a virtual ground applied to the sense resistor divider.
