ESD PROTECTION |
摘要 |
An ESD protection circuit comprises a series connection of at least two protection components between a signal line to be protected and a return line (e.g. ground), comprising a first protection component connected to the signal line and a second protection component connected to the ground line. They are connected with opposite polarity so that when one conducts in forward direction the other conducts in reverse breakdown mode. A bias voltage source connects to the junction between the two protection components through a bias impedance. The use of the bias voltage enables the signal distortions resulting from the ESD protection circuit to be reduced. |

1. An ESD protection circuit comprising a series connection of at least two semiconductor components between a signal line to be protected and a return line, comprising a first protection component connected to the signal line and a second protection component connected to the ground line in series with the first protection component, and a bias voltage source which connects to the junction between the two protection components through a bias impedance.
