    Abstract: Certain aspects of the present disclosure provide methods and apparatus for level shifting an input signal ranging between certain voltage levels to generate an output signal ranging between other voltage levels with low power, high speed, and immunity to noise. One example level-shifting circuit generally includes a node for receiving an input signal ranging between a first voltage level and a second voltage level, a first circuit path coupled to the node and configured to level shift the input signal to generate an output signal ranging between a third voltage level and a fourth voltage level, a pulse generator coupled to the node and configured to generate a pulse based on a transition in the input signal between the first and second voltage levels, and a second circuit path connected in parallel with the first path and configured to temporarily short the first path based on the generated pulse.

    Abstract: An apparatus is disclosed for a switch-mode power supply with a network of flying capacitors and switches. In an example aspect, the apparatus includes a switch-mode power supply with an inductor, a switching circuit, and a network of flying capacitors and switches. The switching circuit is coupled to the inductor. The network of flying capacitors and switches is coupled to the switching circuit and includes at least two flying capacitors and multiple switches. The multiple switches are configured to selectively connect the at least two flying capacitors in parallel between a first terminal of the network of flying capacitors and switches and a second terminal of the network of flying capacitors and switches or connect the at least two flying capacitors in series between the first terminal and the second terminal.

    Abstract: Disclosed is a cascode configuration that moves the gate of the cascode substantially without delay relative to an output node by capacitively coupling the latter onto the cascode gates. The passive coupling eliminates the need for actively driving the gates of the cascode. In some embodiments, the only circuitry needed on the cascode gate may be a biasing circuit that limits the swing on the cascode gate between V max and 2V max , where V max is a transistor device rating.
