Patent number: 9432222Abstract: A transmitter's operation is characterized using components having relatively low cost and low complexity. A device includes comparator(s) that compare a transmitter's analog output to predetermined level(s) to generate count(s) associated with analog output range bin(s). Each of the predetermined levels is associated with a corresponding one of the analog output range bins. A transfer function of the transmitter is generated using the comparison count values associated with the analog output range bin(s). A histogram may be generated from the comparison count values associated with the various analog output range bins. An equalizer is implemented to process data that will be transmitted by the transmitter. The equalizer uses equalizer parameter(s) that are selected based on the characterization of the transmitter (e.g., its transfer function, its histogram, etc.). The equalizer may use default or start up parameters until the transmitter's operation is characterized.Type: GrantFiled: December 26, 2013Date of Patent: August 30, 2016Assignee: BROADCOM CORPORATIONInventors: Ramon Alejandro Gomez, Bruce Joseph Currivan, Lin He, Thomas Joseph Kolze, Franciscus Maria Leonardus van der Goes, Jun Wang

Patent number: 7551035Abstract: A voltage domain crossing circuit and method are disclosed. In one embodiment, the voltage domain crossing circuit comprises an AC coupling component, a DC biasing component and a high voltage output amplifier. The AC coupling component receives an input low voltage signal and AC couples and splits the signal into two voltages.

The high voltage output amplifier then amplifies the biased voltages in the high voltage domain yielding a signal in the high voltage domain. Other embodiments of the voltage domain crossing circuit and method are also disclosed.Type: GrantFiled: August 24, 2006Date of Patent: June 23, 2009Assignee: Broadcom CorporationInventors: Jan Roelof Westra, Franciscus Maria Leonardus van der Goes, Erol Arslan

Patent number: 7262639Abstract: A differential comparator with improved bit-error rate performance operating with a low supply voltage. The differential comparator includes a first pair of transistors receiving a differential input. A second pair of transistors is coupled to the first pair of transistors. A pair of resistive elements is connected between the first pair and second pair of transistors so as to increase bias currents shared by the first and second pairs of transistors. The increased bias currents reduce a time required by the differential comparator to transition from a meta-stable state to a stable state, thereby improving a bit-error rate of the differential comparator. The resistive elements can use linear resistors or transmission gates. Gates of either the first or second pair of transistors can provide an output.Type: GrantFiled: January 21, 2005Date of Patent: August 28, 2007Assignee: Broadcom CorporationInventors: Jan Mulder, Franciscus Maria Leonardus van der Goes, Marcel Lugthart
