Patent ID: 8860509

Claim:
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.
