Analog level meter and method of measuring analog signal level

Abstract

An analog level meter and a method of measuring an analog signal level may be provided. The analog level meter may include a comparator, a duty counter, an analog level detector and/or a digital to analog converter (DAC). The comparator may compare a voltage level of the analog signal with a reference voltage and generate an up-down signal. The duty counter may count a duty value of the up-down signal. The analog level detector may output a duty error value obtained by subtracting a target duty value from the duty value of the up-down signal. The analog level meter may output the reference voltage as a measured value of the analog signal when the duty error value is a desired or predetermined value.
