Abstract :
A CMOS analog interface circuit aimed to condition resistive bridge outputs is presented. It is based on simple and efficient thermal compensation and linearization techniques, providing an amplified, linear output in analog form. Measurement results of a test chip prototype are provided, confirming experimentally the advantages of the circuit.
