ABSTRACT:
A current sense amplifier includes first and second P type MOS transistors having source nodes connected to first and second sensing inputs, respectively, and gate and drain nodes being cross-coupled to each other. First and second N type MOS transistors have drain nodes connected to first and second sensing outputs, respectively, the first and second sensing outputs corresponding to the drain nodes of the first and second P type MOS transistors, respectively, the first and second N type MOS transistors having respective gate nodes connected to a power supply voltage. Third and fourth N type MOS transistors have drain nodes connected to the first and second sensing outputs, respectively, and gate nodes connected to a bias voltage node so that respective current paths are established from the first and second sensing outputs to a common reference node.
