Abstract: Examples direct current-direct current (DC-DC) converter are described. One example DC-DC converter includes three ports and a switch capacitor (SC) circuit. A first port and a second port are input and output ports, and a third port is grounded. The SC circuit includes three capacitors and eight switching transistors. A connection relationship between the three capacitors and eight switching transistors determines that an end of one capacitor in the three capacitors is grounded, and the other two capacitors are connected between the switching transistors.

Abstract: A power system, includes a first switch, a second switch, a first switched capacitor circuit, a second switched capacitor circuit, an inductive voltage conversion circuit, an input end, a first charging end, and a second charging end. An input side of the inductive voltage conversion circuit is coupled to the input end. An output side of the inductive voltage conversion circuit is coupled to the first charging end through the first switch, and is coupled to the second charging end through the second switch. The first switched capacitor circuit is coupled between the input end and the first charging end. The second switched capacitor circuit is coupled between the input end and the second charging end.

Abstract: The technology of this application relates to a clock signal generator, an on-chip clock system, and a chip. The clock signal generator includes a first transistor, a second transistor, a flip-flop, and a power supply end. A first electrode of the first transistor and a first electrode of the second transistor are coupled to the power supply end, and a second electrode of the first transistor and a second electrode of the second transistor are coupled to a common ground. A first input end of the flip-flop is coupled to the first electrode of the first transistor, and a second input end of the flip-flop is coupled to the first electrode of the second transistor. The clock signal generator can make a frequency of an output clock signal more stable.
