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.
