The circuitry comprises a source of input signal current, a common-base transistor amplifier or its equivalent supplying a first load means from its output connection, a first resistive means connected at its first end to the source of input signal current and at its second end to the input connection of the common-base transistor amplifier or its equivalent, a voltage follower with input connection from the first end of the first resistive means, a current mirror amplifier supplying a second load means from its output connection, and a second resistive means connected at its first end to the output connection of said voltage follower and connected at its second end to the input connection of the current mirror amplifier.
