Abstract
An accurate and efficient angle-linear calculation is proposed for three-phase inductive angle-linear. Envelope differences of induced signals on three two-phase receiving coils are demodulated for angle calculation, in order to remove the third harmonic. A circuit architecture is proposed for accurate and efficient angle-linear calculation in which an algorithm is proposed for adaptively outputting envelope differences at a larger slope and then fitting the outputs of envelope differences to straight lines. The proposed method is realized and verified in a 180-nm commplementary metal oxide semiconductor process. Except for efficient angle-linear calculation, the third harmonic and the nonlinearity are improved from -30.9 dB to -92.4 dB and from ±14.8% to ±1.5%, compared with envelopes-based angle-linear calculation.
