The net-grid type analog fractsnee circuit for 1/2 order fractional calculus was put forward and analyzed. The equivalent conversion between T type,Ⅱ type,T type primary fractanee circuit and 1/2 order net-grid type analog primary fractance circuit, the equivalent conversion between syntony crystalloid, cross-linked variable transformer and 1/2 order net-grid type analog primary fractance circuit,and the frequency characteristic of 1/2 order net-grid type analog fractance circuit were disserted. Any fractional order bionic neural-type pulse oscillator was generated with analog fractanee circuit. The results of computer simulation showed that the fractional order bionic neural-type pulse wave accurately simulates actual biology neural-type pulse wave＇s shape characteristic by and large.
