Abstract :
The readout electronics for contact-less inductive position sensors are currently based on discrete solutions. To enhance overall system performance, the implementation of the readout electronics into a single ASIC is desirable. This paper discusses the key system blocks of the analog front-end. Two variants of the mixer architecture for the synchronous detection are examined in terms of their ability to reject phase-sensitive offsets. Simulated results using a 0.35-mum CMOS process technology are presented.
