Abstract: Generation of symmetrical temperature compensated reference voltages in mixed type integrated circuits with a superior PSRR includes the use of a voltage-to-current conversion stage of a temperature independent bandgap voltage for producing eventually a differential pair of currents that are input to a pair of transresistance feedback operational amplifiers the feedback resistors of which are integrated in an interlaced form with a resistor employed in said conversion stage.
