发明名称 Reference voltage generating circuit and constant voltage circuit
摘要 A reference voltage generating circuit for producing a predetermined reference voltage at an output node includes a depletion-type n-channel field-effect transistor serving as a first field-effect transistor having one node thereof coupled to a power supply voltage, a second field-effect transistor having one node thereof coupled to another node of the first field-effect transistor and having a highly-doped n-type gate, and a third field-effect transistor having one node thereof coupled to another node of the second field-effect transistor, another node thereof coupled to a ground voltage, and a highly-doped p-type gate.
