Abstract:
A fingerprint sensing chip and a terminal device are provided. The fingerprint sensing chip includes a first signal, a second signal and a driving signal. The second signal is generated based on the first signal, and the driving signal is generated by performing a ground raise process on the second signal. The driving signal is used to provide a driving voltage for fingerprint sensing.
