IPC: H03F3/343
Filed: 1989-02-16
Abstract: PURPOSE:To improve the detection accuracy with simple constitution by using a current mirror circuit and a band gap low current source, and forming a reference current with high accuracy based on an input current. CONSTITUTION:An input circuit Iin is branched by a bipolar current mirror circuit (CM) 1 and inputted to a CM 2. Transistors(TRs) Q3 and d4 and a resistor Re form a Widler type band gap constant current source BGI, a current I2 of a TR Q2 is proportional to the current Iin, but a current I4 of the TR Q4 changes nonlinearly, and the current I2 becomes smaller/larger than the current I4 depending that the current Iin is smaller/larger than a prescribed threshold level ITH, the output TR Q5 is turned on/off and a current level is detected at a terminal 2. Since the detection threshold level of the current Iin is handled to be a constant except the fluctuation of the resistance Re due to its temperature coefficient, stable detection is attained and the detection accuracy is improved with simple constitution.
