Abstract
The overall performance of a current sense amplifier system may be improved by increasing the common mode rejection of the system. In particular, improved current sense amplifiers may be configured to use a first signal path coupled to the amplifier and a first input terminal, wherein the first signal path is configured to measure the current through a device by generating a voltage proportional to the measured current, wherein the generated voltage includes a small signal voltage with a large common mode voltage, and a second signal path coupled to the amplifier and the first input terminal, wherein the second signal path is configured to reduce the common mode of the generated voltage by level shifting the generated voltage to reduce the common mode voltage.
