Patent number: 9203237Abstract: Circuit protection is provided. In accordance with one or more example embodiments, a thyristor-based circuit and a diode-based circuit are connected in series between an internal circuit terminal and reference terminal, for protecting the internal circuit terminal against circuit stresses such as overvoltage and/or overcurrent, as may be associated with electrostatic discharge. The thyristor and diode-based circuits operate in a first mode at which leakage current is limited by the thyristor, and in a second (protection) mode in which a voltage at the internal terminal exceeds a threshold level at which the thyristor-based circuit operates in a forward-biased mode and the diode operates in a breakdown mode, for shunting current between the internal circuit terminal and reference terminal.Type: GrantFiled: April 24, 2012Date of Patent: December 1, 2015Assignee: NXP B.V.Inventors: Hans-Martin Ritter, Achim Werner

Publication number: 20140160607Abstract: 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.Type: ApplicationFiled: November 5, 2013Publication date: June 12, 2014Applicant: NXP B.V.Inventors: Klaus REIMANN, Hans-Martin RITTER, Wolfgang Schnitt, Anco HERINGA

Patent number: 8686470Abstract: An integrated circuit device provides electrostatic discharge (ESD) protection. In connection with various example embodiments, an ESD protection circuit includes a diode-type circuit having a p-n junction that exhibits a low breakdown voltage. Connected in series with the diode between an internal node susceptible to an ESD pulse and ground, are regions of opposite polarity having junctions therebetween for mitigating the passage of leakage current via voltage sharing with the diode's junction. Upon reaching the breakdown voltage, the diode shunts current to ground via another substrate region, bypassing one or more junctions of the regions of opposite polarity and facilitating a low clamping voltage.Type: GrantFiled: January 7, 2011Date of Patent: April 1, 2014Assignee: NXP, B.V.Inventor: Hans-Martin Ritter
