Title: Clamping circuit
Inventor: TSUCHIYA YOSHITAKA
IPC: H03K5/007
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To prevent a threshold level from being shifted through output amplitude is permitted to be variable by respectively connecting first and second output terminals to the collectors of first and second transistors. SOLUTION: The transistors Q1 and Q2 and a constant current power source I0 constitute a differential circuit (comparator). Resistances R1 and R2 are operated as the load resistance of the differential circuit. Then, the first and the second output terminals 6 and 7 are respectively connected to the collectors of the first and the second transistors Q1 and Q2. The entire collector currents of the transistors Q1 and Q2 are permitted to flow into the resistances R1 and R2. Then, the transistors Q1 and Q2 are comparator-operated with respect to the high level of an output signal and the low level of the output signal. At this time, the current permitted to escape with a diode is not transmitted to a voltage source but a feedback current is permitted to flow at the opposite phase side of a differential output. Thus, the threshold level does not shift, when an output is made variable.
