Abstract

PURPOSE:To obtain the excellent limiter characteristics capable of a high-speed operation, by delivering the input signal directly in case the level's absolute value of the input signal is smaller than the fixed value and then clamping the input signal with the fixed level in case the absolute value is larger than the fixed value respectively. CONSTITUTION:Reference voltage sources E1, E2 are connected to emitter electrodes of switching transistors (TR)Q3, Q4 each, and both the collectors are connected to power sources +B and -B via resistances R3, R4 each. Here voltages E1, E2 have an equal voltage level each other with the different polarities. And in case the base-emitter voltage of TRQ3, Q4 is set to VBE and when the level absolute value of the input signal is smaller than E+VBE, TRQ3, Q4 are turned off. And the input signal is delivered without clipping. When the level absolute value of the input signal becomes larger than E+VBE, TRQ3 or Q4 conducts. And the base electrode is clamped to the level of E+VBE. In such way, the excellent limiter characteristics capable of a high-speed operation can be obtained.
