Abstract
A voltage regulator having current sense capability may include an input node and an output node. A first output device may be electrically connected between the input node and the output node, and configured to control current flow through the first output device to regulate a voltage at the output node. A current sense circuit may be configured to produce a signal that is indicative of the current through the first output device. The current sense circuit may be configured to perform a first kind of offset compensation operation to reduce an offset voltage in an error amplifier of the current sense circuit, and to perform a second kind of offset compensation operation to reduce the offset voltage in the error amplifier.
