Abstract

Disclosed herein is a signal level conversion circuit for increasing the dynamic range of an Analog-to-Digital Converter (ADC). A comparison and calculation unit compares the value of an input signal Vand the value of a first reference signal Vand compares the value of the input signal Vand the value of a second reference signal V, and calculates and outputs respective differences therebetween. A signal leveling circuit unit converts signal levels of the respective output signals of the comparison and calculation unit so that the output signals fall within the dynamic range of an ADC. The ADC digitizes the output signal Vof the signal leveling circuit unit and the output signals Vand Vof the comparison and calculation unit.
