Abstract
A band-gap referenced voltage circuit with smaller parasitic resistance which brings reduced band-gap error is disclosed. This reduced error stems from the unique configuration of stacked diode and a shorter wiring line to a resistor. The band-gap referenced voltage circuit includes two diodes, an operational amplifier with non-inverting and inverting inputs and an output for the band-gap voltage output, and three resistors. Employing the stacked configuration of the diode with the top anode electrode, the wiring line which connects the non-inverting input of the operational amplifier and the voltage reference diode is made short. Then the resistance of the wiring line, called also parasitic resistance, would be small.
