Abstract
One example relates to a monitoring circuit that includes a capacitive digital-to-analog converter that receives a binary code, a reference voltage, a monitored voltage, and a ground reference, the capacitive digital-to-analog converter outputting an analog signal based on the binary code, the reference voltage, the monitored voltage, and the ground reference. The monitoring circuit further includes a comparator including a first input coupled to receive the analog signal and a second input coupled to the reference voltage, the comparator comparing the analog signal to the reference voltage and outputting a comparator signal based on the comparison. The monitoring circuit yet further includes a binary code generator that generates the binary code based on the comparator signal, the binary code approximating a magnitude of the monitored voltage.
