1. An oscillator, comprising:
a resonant circuit, configured to generate an oscillator signal;
a first cross-coupled transistor, coupled to the resonant circuit;
a power supply circuit, configured to supply a power supply signal for the first cross-coupled transistor based on a first voltage and a second voltage, wherein the first voltage is a power supply voltage, and the second voltage is a voltage generated by an external sensing circuit based on a mechanical pressure or a mechanical vibration; and
wherein the power supply signal is a voltage signal, the power supply circuit comprises an adder, and the adder is configured to add the first voltage and the second voltage to obtain the voltage signal.
