Ampere-level driving signal generation circuit and method with adjustable amplitude and frequency

The invention discloses an amplitude and frequency adjustable ampere-level driving signal generation circuit and method. Different voltage values are generated by using a two-channel direct-current power supply; the reference grounds of the two channel voltages (different voltage values) are isolated by using the isolation characteristics of the source electrode and the drain electrode of the MOS tube, and a square wave (signal) generator is used for controlling the gate electrode of the MOS tube to open and close the source electrode and the drain electrode of the MOS tube; and driving signals with different amplitudes are generated by adjusting the voltage amplitude of the direct-current power supply. The problems that a programmable power supply cannot generate a high-frequency square wave signal and a signal generator cannot generate a power signal with ampere-level output current capability are effectively solved, and a driving signal with adjustable frequency and amplitude can be directly generated only
