<p>A circuit for generating a reference electrical quantity ( I REF , V REF ) , including: a first bipolar transistor (T bjt1 ) and a second bipolar transistor (T bjt2 ) having the base terminals connected to one another and to a common node (N C ) ; a first resistor (R A ) connected to the emitter terminal of the second bipolar transistor (T bjt2 ); a first mirror circuit and a second mirror circuit (T 1 , T 2 , T s1 , T s3 , T m , T s2 , T s4 ) connected to the first and second bipolar transistors (T bjt1 , T bjt2 ) , which receive, respectively, a first current (I PTAT) and a second current (I NTAT ) and generate, respectively, a first mirrored current (³I PTAT ) and a second mirrored current (±I NTAT ); a first output stage (6, 8), which generates the reference electrical quantity (I REF , V REF ) as a function of the first and second mirrored currents (³I PTAT ±I NTAT ) and a second resistor (R B ) connected to the common node (N C ). The first current (I PTAT ) is a function of the current in the first resistor (R A ), whilst the second current (I NTAT ) is a function of the current in the second resistor (R B ).</p> |
