Abstract: The application provides an apparatus, a system, a detector and a method. The apparatus includes: a power supply voltage detector, including: N buffers, an input terminal of a first buffer being connected to a clock signal, output terminals of other buffers being connected to the input terminal of an adjacent buffer; N latch chains, each of which includes M latches, a clock input terminal of each latch being connected to a clock signal, a D terminal of a first latch of each latch chain being connected to the output terminal of a corresponding buffer, Q terminals of other latches being connected to the D terminal of an adjacent latch, M and N being positive integers, the D terminal of each latch being connected to an area where a power supply voltage is to be detected; and a voltage regulation module connected to the Q terminal of each latch.
