The invention discloses a pulse separating circuit for a motorcycle igniter and relates to a motorcycle ignition circuit. The pulse separating circuit mainly comprises a positive pulse processing circuit, a negative pulse processing circuit, two pulse comparison amplifiers, two Schmidt triggers and a discharge circuit. In the pulse separating circuit for the motorcycle igniter, the pulse separating circuit and a motorcycle automatic angle-advancing control circuit are integrated into the same chip, so that the problems of too many peripheral elements, inconvenient debugging, high cost and the like in the universal ignition circuit are solved. Furthermore, in the circuit, pulse separation is realized by adopting the two-stage amplifiers so that the minimum rotary speed (less than 50 r/min) of motorcycle ignition is greatly reduced.

The invention discloses a SiC-based MOSFET (metal-oxide -semiconductor field effect transistor) oxysensible sensor for an automobile engine and a manufacturing method thereof. Silicon carbide material with the excellent characteristics of wide energy gap, high breakdown electric field, high electron saturated drifting velocity, high heat conductivity and the like is used as a P-type substrate of an N-type channel MOSFET, thereby meeting the requirement of high-temperature working. In the MOSFET structure, a layer of oxysensible film material (such as YSZ: yttria stabilized zirconia) grows on an original gate oxide layer, wherein metal Pt is adopted as a metal gate electrode, and the channel of a MOSFET type oxysensible sensor can be a surface channel and an embedded channel. In the sensor, the change of oxygen concentration can be converted into the change of capacitance of the gate oxide layer in unit area, thereby causing the change of a threshold voltage. Besides, the invention also ...
