Abstract
The semiconductor device according to this disclosure includes an analog input terminal, an amplifier circuit, a sample-and-hold circuit, an analog input switch connected between the analog input terminal and the input terminal of the amplifier circuit, a control switch connected between the output terminal of the amplifier circuit and the input terminal of the sample-and-hold circuit, a comparison circuit connected to the output terminal of the sample-and-hold circuit, an analog-to-digital converter connected to the comparator circuit, a control circuit, and a signal conversion circuit for converting the first control signal from the control circuit into a second control signal. The analog input switch is turned on during the activation level of the second control signal. The period of the activation level of the second control signal is longer than that of the first control signal to reduce a conversion error of an analog-to-digital conversion circuit.
