Abstract
In a constant current circuit, a drain terminal is connected to an output terminal of a current, and a gate voltage operable in a saturation region is applied to a source-grounded transistor. An increase current generating circuit generates an increase current equivalent to an increase of a current due to a channel length modulation effect of the transistor. A current mirror circuit generates a current having the same value as that of the increase current generated by the increase current generating circuit and supplies the generated current to the drain terminal of the transistor.
