Abstract
A circuit chip with power supply noise rejection includes a switch unit, an energy storage unit, and an operating circuit. The switch unit has a first connection terminal and a second connection terminal. The first connection terminal is adapted to receive a power supply voltage. The switch unit is configured to selectively turn on a first connection path between the first connection terminal and the second connection terminal according to a clock signal. The energy storage unit is coupled to the second connection terminal. When the switch unit turns on the first connection path, the energy storage unit is configured to generate a storage voltage on the second connection terminal according to the power supply voltage. The operating circuit is coupled to the second connection terminal, and the operating circuit is configured to operate according to the storage voltage.
