<p>An integrated circuit device includes a differential to single-ended voltage converter having multiple current mirrors ([106, 206, 306, 108, 208, 308, 220, 320, 224, 324, 226, 326). Each of the current mirrors is configured to be activated to provide a current or deactivated based on a common mode of a first and second input voltage at the converter. A current based on the combined current generated by the current mirrors is applied to a resistor to generate a single-ended output voltage. The output voltage represents a difference between the first input voltage and the second input voltage. In addition, one or more of the current mirrors can be configured to be active even when a common mode of the input voltage is outside the supply voltage range for an integrated circuit device. Accordingly, the voltage converter can provide a single-ended voltage representative of the differential input voltage even when a common mode of the input voltage exceeds the supply voltage range.</p> |
