LOW POWER AND HIGH ACCURACY BAND GAP VOLTAGE REFERENCE CIRCUIT |
摘要 |
A band gap voltage reference circuit includes a first band gap circuit configured to generate a first band gap voltage potential. A second band gap circuit includes a variable resistance. The second band gap circuit is configured to output a second band gap voltage potential based on a value of the variable resistance. A calibration circuit is configured to adjust the variable resistance of the second band gap circuit based on the first band gap voltage potential and the second band gap voltage potential. The first band gap circuit is shut down in response to the second band gap voltage potential being within a predetermined range of the first band gap voltage potential.
