Clipping circuit, differential amplifying circuit, and amplifying circuit

A clipping circuit, comprising:

• a first input terminal to receive a first signal, a pair of the first signal and a second signal forming a differential signal as a clipping target;
• a second input terminal to receive the second signal;
• a first variable resistive element having a control terminal electrically connected to the second input terminal and having a threshold, a first end of the first variable resistive element being connected to the first input terminal and a second end of the first variable resistive element being connected to a reference voltage;
• a second variable resistive element having a control terminal electrically connected to the first input terminal and having a threshold, a first end of the second variable resistive element being connected to the second input terminal, and a second end of the second variable resistive element being connected to the reference voltage;
• a first bias applying unit to apply a bias voltage lower than the threshold of the first variable resistive element to the control terminal of the first variable resistive element;
• and
• a second bias applying unit to apply a bias voltage lower than the threshold of the second variable resistive element to the control terminal of the second variable resistive element.
