Abstract:
1. A voltage converter responsive to a differential input signal comprising a first and a second input signal, the converter for producing a differential output signal in response to the differential input signal, the converter comprising: a first input module responsive to the first and the second input voltages; a second input module responsive to the first and the second input voltages; a first and a second current supplying module, the first input module biases the first current supplying module at a first bias current through the first current supplying module and biases the second current supplying module at a second bias current through the second current supplying module, wherein the first current is greater than the second current; a third and a fourth current supplying module, wherein the second input module biases the third current supplying module at a third bias current through the third current supplying module and biases the fourth current supplying module at a fourth bias current through the fourth current supplying module, wherein the fourth current is greater than the third current; and wherein the differential output voltage comprises a first and a second output voltage responsive to the first, second, third and fourth currents.
