Abstract
The circuit includes a differential voltage/current converter (V/I) for connection to the sensor (S), a differential transresistance amplifier (TDA) whose inputs are connected to the outputs of the converter (V/I), and a double-ended/single-ended converter (D/S) connected to the outputs of the amplifier (TDA). The circuit is conveniently formed as an integrated circuit by CMOS P-well technology.
