Title: Hysteresis comparator
Inventor: NAGASE NAOKI
IPC: H03K5/13
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To enhance the hysteresis characteristic of a hysteresis comparator. SOLUTION: A comparator 12 compares an input signal VI with a reference signal VA so as to output a signal V0. The ratio of the emitter area of a transistor T11 to that of a transistor T12 at a hysteresis circuit 13 is 1:n. A switch 15 is turned on and off by the signal V0 so as to supply and cut off a current to the transistors from a constant-current source 14. A voltage source V1 and a resistance R1 are connected to the emitter of the transistor T11, a resistance R2 is connected to the emitter of the transistor T12, and a resistance R3 is connected to a voltage source V2. The reference signal VA is output from the connection point of the resistances R1 to R3. The collector and the base of the transistor T11 are connected, and the collector and the base of the transistor T12 are connected.  The current of the constant-current source 14 is set at (n+1)/n times as large as a current flowing in the transistor T12 so that the emitter voltage of the transistor T12 becomes equal to the voltage source V1.
