Patent number: 11121893Abstract: A transmitter for providing channel equalization that includes a first driver and second driver having a high pass filter. The first driver generates a first output signal representing a digital input signal. The second driver generates a second output signal representing a high pass filtered version of the digital input signal. The first and second output signals are summed to provide a third output signal that is channel equalized for transmission over a channel.Type: GrantFiled: November 15, 2019Date of Patent: September 14, 2021Assignee: Rambus Inc.Inventor: John Wood Poulton

Patent number: 8363368Abstract: A power supply shunt for an electronic circuit. The power supply shunt includes at least two Field Effect Transistors (FETs), a first of the FETs having its drain coupled to a terminal of an electronic circuit and its source coupled to another of the FETs, and a second of the FETs having its source coupled to ground and its drain coupled to another of the FETs. The first FET has a bulk terminal that floats with respect to ground.Type: GrantFiled: November 9, 2011Date of Patent: January 29, 2013Assignee: Rambus Inc.Inventor: John Wood Poulton
