1. A power regulation apparatus, comprising:
a first switch; and
a switch control signal generation unit comprising:
a first transconductance unit comprising a first input terminal for receiving a first voltage from a first terminal of the first switch, a second input terminal for receiving a second voltage from a second terminal of the first switch, and an output terminal for being connected to a first node;
a node voltage generation unit connected to the first node and configured to generate a node voltage signal at the first node; and
a second transconductance unit comprising a first input terminal for receiving a current characterization signal characterizing a current flowing through the first switch, a second input terminal for being connected to the first node to receive a node voltage signal, and an output terminal for being connected to a control terminal of the first switch.
