Sensor XOR 5- A power supply circuit system using a negative threshold five-terminal NMOS FET device with multiple step connection for XOR logic operation of Sensor signal

摘要

There is no constitution of another ordinary transformer circuit and a structure of a zener diode element in a voltage converting apparatus for converting AC and DC power from a high voltage to a low voltage direct current power and the voltage between negative gate sources The structure of a depletion NMOS (N-type metal oxide semiconductor) field effect transistor (FET) having a negative threshold voltage, a 5-terminal NMOS transistor (negative threshold 5-terminal NMOS FET). The circuit area of the transformer circuit 100 and the Zener diode 104 is removed to remove the area occupied by the circuit area of the transformer circuit 100 and the Zener diode 104, It is possible to implement a cost circuit and realize a circuit without power consumption in standby and operation power supply state by interrupting standby and operation power loss and to realize free voltage operation up to high voltage supply region As shown in FIG.In addition, the amplification and power supply device is capable of stably detecting and amplifying a signal of a sensor element whose output signal is weak.;
