Abstract:
A current generating circuit comprising:a first transistor connected between a first supply terminal and a node directly or by way of another element;a total of k first elements (0.ltoreq.k .ltoreq.n (where n is 0 or a natural number)) connected between said first supply terminal and said node directly or by way of another element;a total of n-k second elements connected between said node and a second supply terminal directly or by way of another element;a control circuit for setting a potential of said node to a predetermined level; anda second transistor having a source connected to said first supply terminal directly or by way of another element and a gate connected to a gate of said first transistor and adapted to generate a second current by using a first current flowing to said first transistor as a reference, the first current flowing to said first transistor showing a current value equal to the value obtained by subtracting the sum of currents flowing to the respective k first elements from the sum of currents flowing to the respective n-k second elements.
