摘要： In an example, a circuit includes a high side output transistor having a control terminal coupled to a first capacitor, and includes a low side output transistor having a control terminal coupled to a second capacitor and a balancing capacitor. The circuit includes a first differential input stage configured to receive a differential input and provide a first output current to the control terminal of the high side output transistor. The circuit includes a second differential input stage configured to receive the differential input and provide a second output current to the control terminal of the low side output transistor. The circuit includes a floating battery coupled to the control terminal of the high side output transistor and the control terminal of the low side output transistor. The balancing capacitor balances a gate-to-source capacitance of the low side output transistor with a gate-to-source capacitance of the high side output transistor.
