  • Reference voltage generator based on threshold voltage difference of field effect transistors
    Patent number: 11614763
    Abstract: An aspect of the disclosure relates to a reference voltage generator, including: a first field effect transistor (FET) including a first threshold voltage; a second FET including a second threshold voltage different than the first threshold voltage; a gate voltage generator coupled to gates of the first and second FETs; a first current source coupled in series with the first FET between first and second voltage rails; a second current source; and a first resistor coupled in series with the second current source and the second FET between the first and second voltage rails, wherein a reference voltage is generated across the first resistor.
