An apparatus including cascaded amplification stages adapted to be biased by a common DC current to generate an amplified output signal from an input signal. A first amplification stage includes a routing network to substantially double an input voltage signal, and a first transconductance gain stage to generate a first current signal from the input voltage signal. A second amplification stage includes a resonator to convert the first current signal into a second voltage signal, and a second transconductance gain stage to generate a second current signal from the first current signal. A third amplification stage includes a current gain stage to generate a third current signal from the second current signal, and a load through which the third current signal flows to generate the output signal.
