Abstract :
The use of integrated circuit techniques in position sensing applications can offer significant advantages over discrete component solutions, such as miniaturization, reduced cost, increased reliability and enhanced sensitivity. We realized a signal conditioner that includes an application specific integrated circuit (ASIC) and an external microcontroller for readout and control of non-contact high-frequency inductive position sensors. Both the system architecture and details on the key blocks are described. The ASIC was designed in a 0.6-¿m CMOS process technology and preliminary measured results are presented. The signal conditioner architecture is universal and can be used for other sensor types such as LVDTs.
