Abstract: A circuit for use, e.g., as current sense amplifier in a DC-DC converter in a hybrid vehicle includes a first input node and a second input node, configured to have an input voltage signal applied therebetween, a floating-ground input stage configured to operate between a first supply voltage and a second non-zero supply voltage and to convert into a current signal the input voltage signal applied between the first input node and the second input node. The circuit includes an output stage configured to receive the current signal from the floating-ground input stage and to convert the current signal back to an output voltage signal referred to ground. The output voltage referred to ground is a replica of the input voltage signal applied between the first input node and the second input node.
