Abstract :
A simple enhanced current mirroring circuit is presented which enables improvement of the S/N ratio in analogue circuits. Three transistors are added to the conventional mirror, and no additional power is needed. A reduction of >20 dB in the sensitivity to high frequency parasitic signals can easily be obtained
