ABSTRACT:
A semiconductor integrated circuit includes a current source for supplying a current i, a resistor, a switch having a control end connected to the resistor, an output terminal connected to the output end of the switch, a comparator having a current path which is connected at one end to a connection node between the resistor and the control end of the switch and connected at the other end to the output terminal. The comparator compares a voltage (i.times.R) occurring across the resistor with a potential V of the output terminal and permits the current i to flow into the output terminal when the relation (i.times.R.gtoreq.V) is attained.
