1. A method for operation of a high-voltage signal amplifier, the method comprising:
inputting, into each transconducting cell of a plurality of transconducting cells, a direct current (DC) supply current (Idc), an alternating current (AC) radio frequency (RF) input current (IRF_IN), and an RF input signal (RFIN); and
outputting, by each of the plurality of transconducting cells of the plurality of transconducting cells, the DC supply current (Idc) and an AC RF output current (IRF_OUT),
wherein the plurality of transconducting cells are connected together in cascode for the DC supply current, and are connected together in cascade for the AC RF input and output currents.
