低功率小面积基于振荡器的ADC
摘要：
在一个实施例中，一种用于测量电流的方法包括基于正被测量的电流来生成传感器电流。该方法还包括将组合电流转换成第一频率，其中组合电流是传感器电流与共模电流之和，以及将该第一频率转换成第一计数值。该方法进一步包括将共模电流转换成第二频率、将第二频率转换成第二计数值、以及从第一计数值中减去第二计数值以获得电流读数。
摘要（英）：

In one embodiment, a method for measuring current comprises generating a sensor current based on a current being measured. The method also comprises converting a combined current into a first frequency, wherein the combined current is a sum of the sensor current and a common-mode current, and converting the first frequency into a first count value. The method further comprises converting the common-mode current into a second frequency, converting the second frequency into a second count value, and subtracting the second count value from the first count value to obtain a current reading.
