Abstract: A driving device includes a first current source, a second current source, a first common-mode current elimination (CMCE) circuit, a second common-mode current elimination (CMCE) circuit, a current-to-voltage converter, and a first comparator. The current sources provide constant currents. The current-to-voltage converter includes a first current mirror and a second current mirror. The control terminal of the first current mirror is coupled to the second CMCE circuit. The control terminal of the second current mirror is coupled to the first CMCE circuit. The first current mirror and the second current mirror receive the constant currents, common-mode currents, and differential currents, thereby controlling the first CMCE circuit and the second CMCE circuit to generate a voltage difference that excludes a common-mode voltage corresponding to the common-mode currents. The first comparator receives the voltage difference to drive a field-effect transistor.
