Document Type and Number:
Japanese Patent JP2768855
Kind Code:
B2
Abstract:
A semiconductor integrated circuit includes a current source (1) for supplying a current i, a resistor (2), a switch (3) having a control end connected to the resistor (2), an output terminal (4) connected to the output end of the switch, a comparator (5) having a current path which is connected at one end to a connection node between the resistor (2) and the control end of the switch (3) and connected at the other end to the output terminal (4). The comparator (5) compares a voltage (i x R) occurring across the resistor (2) with a potential V of the output terminal (4) and permits the current i to flow into the output terminal (4) when the relation (i x R >/= V) is attained.
