Abstract
A passive conjunction circuit for an analog-to-digital converter (ADC) is disclosed. In one aspect, the passive conjunction circuit includes a first input node receiving an analog input signal to be converted by the ADC and a second input node receiving a reference voltage other than a ground voltage of the ADC. The passive conjunction circuit also includes a first output node to be connected to a first differential input of the ADC (20) and a second output node to be connected to a second differential input of the ADC. The passive conjunction circuit further includes a first voltage divider interconnected between the first input and output nodes and a second voltage divider interconnected between the second input and output nodes.
