| Abstract: | Using two orthogonal full bridge GMR sensor chips SAS012 to generate a pair of quadrature signals, then using FPGA chip EP1C6PO240, a magnetic encoder is designed. The pipelined CORDIC algorithm can be very good to meet the real-time requirements of the system; and further digital filter technology is used in the prototype. The test results show that the magnetic output is very stable. |
