Voltage reference generation circuit using gate-to-source voltage difference and related method thereof |
摘要 |
A voltage reference generation circuit includes a current supply circuit and a core circuit. The current supply circuit is arranged to provide a plurality of currents. The core circuit is coupled to the current supply circuit, and arranged to receive the currents and accordingly generate a voltage reference. The core circuit includes a first transistor, a second transistor and a third transistor, wherein the first transistor and the third transistor generate a first gate-to-source voltage and a third gate-to-source voltage, respectively, according to a first current of the received currents; the second transistor generates a second gate-to-source voltage according to a second current of the received currents; and the voltage reference is generated according to the first gate-to-source voltage, the second gate-to-source voltage and the third gate-to-source voltage. |
