CONSTITUTION:When the amplitude of an input signal is small, an amplitude detecting circuit 10 gives a detected output of a comparatively low voltage to a variable DC voltage source 11. Thus, the voltage source 11 gives a DC bias voltage comparatively low to an adder circuit 12 in response to the detected output. The circuit 12 superimposes a DC bias voltage on the input signal and gives the result to the limiting amplifier circuit 1. A DC bias voltage in response to the amplitude of the input signal is added to the DC bias voltage given in advance at the circuit 1. Then, the DC bias voltage according to the amplitude of the input signal is given to the circuit 1. Since the DC bias voltage is changed in response to the input signal, the operating point of the circuit 1 is changed in response to the DC bias, the duty of the outputted waveform at the DC level is brought to 50%, allowing to reduce the even order harmonic.,下面是Limiting amplifier专利的具体信息内容。
