    摘要： A switching control circuit for a DC-DC converter comprises an input terminal to receive input signals and an output terminal to couple the switching control circuit to a switch of the DC-DC converter. A quasi-static supply path is coupled to the input terminal to receive first signals based on the input signals and coupled to the output terminal to provide output signals to the output terminal based on the input signals. A dynamic supply path is coupled to the input terminal to receive second signals based on the input signals in-phase with the first signals and coupled to the output terminal to provide output signals to the output terminal based on the input signals.

    摘要： A current-saving differential wideband driver circuit comprises a differential input amplifier for amplifying a differential input signal to produce a differential intermediate signal being comprised of a first intermediate signal and a second intermediate signal, a first transimpedance amplifier comprising a first inverting input, a first non-inverting input, and a first output, and a second transimpedance amplifier comprising a second inverting input, a second non-inverting input, and a second output. The first intermediate signal is applied to the first non-inverting input, the first output is connected to the first inverting input of the first transimpedance amplifier via a first feedback resistor for negative current feedback, the second intermediate signal is applied to the second non-inverting input, and the second output is connected to the second inverting input of the second transimpedance amplifier via a second feedback resistor for negative current feedback. The differential wideband driver circuit further comprises a third feedback resistor connected between the first and second inverting inputs for setting a gain factor for the wideband driver circuit and an amplified differential output signal is present at the first and second outputs.
