Abstract :
A current-mode multiplexer for interrogating resistive sensor arrays has been fabricated in a commercial 2 μm BiCMOS process under the EUROCHIP initiative. The multiplexer allows a programmable voltage to be forced across the required sensor(s) and the resulting current can be offset by a programmable current source. Control of the device is via a simple serial digital interface
