A current mirroring circuit is provided. The circuit generally comprises a current source; a first drain extended (DE) MOS transistor, a second DE MOS transistor, a current mirror, and differential amplifier. The current source is generally coupled to the current source at its drain, while the current mirror that is coupled to the sources of the first and second DE MOS transistors and to the current source. The differential amplifier generally has a first input that is coupled to the source of the first DE MOS transistor, a second input that is coupled to the source of the second DE MOS transistor, a first output that is coupled to the gate of the second DE MOS transistor, and a second output that is coupled to the gate of the first DE MOS transistor. |
