1. Gate controller (100) for a charge pump converter stage (101), said charge pump converter stage (101) comprising at least one switching element (110) having a conduction path (115) with a first terminal (111) and a second terminal (112), and a gate (113) configured to control the current flowing through said conduction path (115), said conduction path (115) being configured to provide at least one signal; said gate controller (100) comprising at least:
one primary signal input (120): said at least one primary signal input (120) is directly connected to a second terminal of another charge pump converter stage to receive a signal from said another charge pump converter stage and to transfer said signal to said first terminal (111) of conduction path (115) of said at least one switching element (110);
at least one bias input (130): said at least one bias input (130) is connected to said gate (113) through a resistor (131) and configured to establish a voltage value and/or a current value of said gate (113); and
at least one coupling capacitor (140) configured to connect said gate (113) to said at least one primary signal input (120) and to connect said conduction path (115) of said at least one switching element (110) to said gate (113).
