Abstract
A compact resolver pre-amplification assembly has first and second printed circuit boards. The boards include an interface with an N/N−1 resolver and a resolver-to-digital converter and three signal paths. The first and second circuit boards are contained in a single package configured for mounting on a robotic joint while providing high amplification and noise rejection. Low level sensitive signal are separated from high level excite signals by locating sensitive signals on the first board and excite signals on the second board.
