| 发明名称 | System and method for calibrating a circuit | ||
| 摘要 | In accordance with an embodiment, a method of calibrating a circuit includes coupling a first reference voltage to a first input of the circuit, coupling a programmable reference voltage to a reference node of a digital-to-analog converter (DAC), such that the gain of the DAC is dependent on an input value at the reference node. The method further includes providing a first predetermined input code to the DAC, summing an output of the DAC with the first reference voltage to produce a summed output, comparing the summed output to a threshold, and adjusting the programmable reference voltage until the summed output is within a predetermined range of the threshold. | ||

| 主权项 | 1. A method of calibrating a circuit, the method comprising: coupling a first reference voltage to a first input of the circuit; coupling a programmable reference voltage to a reference node of a digital-to-analog converter (DAC), wherein a gain of the DAC is dependent on an input value at the reference node; providing a first predetermined input code to the DAC; summing an output of the DAC with the first reference voltage to produce a summed output; comparing the summed output to a threshold; and adjusting the programmable reference voltage until the summed output is within a predetermined range of the threshold. | ||
