ABSTRACT:
A current mirror having a high output voltage swing and which uses only one reference current source. The current source provides an output current that is substantially equal to the reference current and, as such, does not suffer from a current offset. The current mirror achieves body-effect cancellation, permits easy scaling of current consumption and provides for fast charging and discharging of the bias lines.
