Patent number: 9325313Abstract: A low-power level-shift circuit for data-dependent signals includes a buffer circuit, a coupling capacitor, and a biasing circuit. The buffer circuit is biased by a low-voltage domain voltage supply and configured to receive a data-dependent signal. The coupling capacitor is coupled, at a first node, to an output node of the buffer circuit. The biasing circuit is coupled to a second node of the coupling capacitor and a switch. The level-shift circuit can translate a voltage level of the received data-dependent signal to a high-voltage domain that is suitable for proper operation of the switch.Type: GrantFiled: February 20, 2014Date of Patent: April 26, 2016Assignee: Broadcom CorporationInventors: Franciscus Van Der Goes, Christopher Michael Ward

Publication number: 20070176664Abstract: A programmable gain attenuator (PGA) in particular to be used in a track-and-hold circuit is disclosed. The PGA is located in the feedback path around an operational amplifier. One tap switch is used to connect one PGA section to the output of the operational amplifier. The PGA section is capable of producing a multiplicity of different gain settings by using a multiplicity of secondary resistive devices in a voltage divider, wherein the resistive devices each can be independently coupled to a reference voltage.Type: ApplicationFiled: January 30, 2006Publication date: August 2, 2007Applicant: Broadcom CorporationInventors: Ovidiu Bajdechi, Franciscus van der Goes

Publication number: 20060164126Abstract: 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: ApplicationFiled: January 21, 2005Publication date: July 27, 2006Inventors: Jan Mulder, Franciscus van der Goes, Marcel Lugthart

Publication number: 20050162195Abstract: A method for reducing bit errors in an analog to digital converter having an array of comparators. The outputs of first and second comparators are received as in inputs to an Exclusive OR gate. The first and second comparators are separated in the array by a third comparator. The output of the Exclusive OR gate is used to determine if the third comparator is in a metastable condition. If the third comparator is in a metastable condition, the bias current of the latch circuit of the third comparator is increased to increase the rate at which the third comparator transitions to a steady state.Type: ApplicationFiled: March 24, 2005Publication date: July 28, 2005Inventors: Jan Mulder, Franciscus van der Goes
