Abstract :
A negative current mirror suitable for monolithic IC fabrication is described. It is unusual in that it is a `voltage-following¿ circuit in which the input-output offset voltage is small and only weakly dependent on operating conditions. A base-current compensation scheme enables the circuit to exhibit a current transfer ratio comparable with that of the `Wilson¿ current mirror.
