Abstract
A buffer apparatus, a chip and an electronic device. The apparatus comprises: a voltage adjustment module () comprising a first P-type metal-oxide-semiconductor field-effect transistor (PMOS), wherein the voltage adjustment module () is used for receiving an input voltage, using a threshold voltage for the first PMOS to adjust the input voltage, and outputting a driving voltage; and a buffer module () electrically connected to the voltage adjustment module () and used for receiving an input signal, buffering the input signal under the driving voltage, and outputting a buffered signal. The driving voltage obtained by using the threshold voltage for the first PMOS to adjust the input voltage can compensate for a process corner of the buffer module (), such that the range of a flip point voltage of the buffer module () becomes small and meets process requirements.
