Abstract (en)

[origin: US2017153659A1] An FDSOI reference voltage generation circuit, including a CTAT current generation circuit; a PTAT-type voltage generation circuit including a first branch including first and second series-connected transistors, the front surface gates of the first and second transistors being connected to the conduction node of the second transistor opposite to the first transistor; a third diode-assembled transistor having a conduction node connected to an output node of the PTAT voltage generation circuit and having its other conduction node forming a reference voltage supply node; and a current mirror; wherein the first and second transistors are of LVT type and the third transistor is of RVT type.
