Patent number: 11791831Abstract: Systems and methods for fault-tolerant threshold circuits used in converting an analog input to a single-bit digital output employ N-modular redundancy of either inverting or non-inverting threshold circuits whose inputs are connected to a single input, and apply majority voting of their outputs to provide correction of transient or permanent faults in up to floor[(N?1)/2] of the individual threshold circuits. Using summation to perform analog majority voting averages the N threshold circuit outputs and provides resilience to single-event transients, but may exhibit an output characteristic having intermediate voltage levels. A digital majority voter having N inputs connected to the outputs of N threshold circuits restores well-defined logic levels and clean hysteresis for Schmitt trigger threshold circuits. A single point of failure at the digital majority voter may be eliminated using an analog majority voter to sum the outputs of three or more redundant digital majority voters.Type: GrantFiled: May 19, 2023Date of Patent: October 17, 2023Assignee: Apogee Semiconductor, Inc.Inventors: David A.

Patent number: 7584370Abstract: A semiconductor network is interposed between first and second multiple-port interfaces each having high-voltage, intermediate-voltage and ground ports to form a switch assembly. The assembly includes a primary switch circuit, a support network, internal and external-port circuits and internal and external-port control circuits. The primary switch circuit is coupled to high-voltage ports of the multiple-port interfaces and to the support network. The internal and external-port circuits are coupled to intermediate-voltage ports of the multiple-port interfaces, the internal and external-port control circuits and the support network. The internal-port control circuit is coupled to the internal-port circuit, the support network and a ground port of a first multiple-port interface. The external-port control circuit is coupled to the external-port circuit, the support network and a ground port of the second multiple-port interface.Type: GrantFiled: June 22, 2006Date of Patent: September 1, 2009Assignee: Skyworks Solutions, Inc.Inventor: Bin Zhao

Patent number: 7511535Abstract: A power management circuit is provided for controlling power dissipation in at least one combinational logic circuit. The power management circuit includes a detector operative to receive at least a first input signal to the combinational logic circuit and to detect a transition of the first input signal between a first logic state and a second logic state. The detector generates a control signal indicative of whether or not a transition of the first input signal has occurred.Type: GrantFiled: February 28, 2007Date of Patent: March 31, 2009Assignee: Agere Systems Inc.Inventors: Kanad Chakraborty, Steven E. Strauss, Bingxiong Xu

Patent number: 7451384Abstract: A system and method for providing error recovery to an asynchronous logic circuit is presented. The asynchronous logic circuit with error recovery may use temporal redundancy to compare the results of an asynchronous computation and initiate error recovery if necessary. Outputs of the asynchronous logic circuit are compared using a plurality of asynchronous register voters. If an asynchronous register voter detects an inconsistent result, the asynchronous register voter clears itself. A majority of common data outputs from the plurality of asynchronous register voters is provided as an output that is representative of the output of the asynchronous logic circuit.Type: GrantFiled: July 15, 2004Date of Patent: November 11, 2008Assignee: Honeywell International Inc.Inventors: David O. Erstad, Roy M. Carlson

Patent number: 7276932Abstract: Virtual power-gated cells (VPC) are configured with control circuitry for buffering control signals and a power-gated block (PGB) comprising two or more NFETs for virtual ground rail nodes and PFETs for virtual positive rail nodes. Each VPC has a control voltage input, a control voltage output, a node coupled to a power supply voltage potential, and a virtual power-gated node that is coupled and decoupled from the power supply potential in response to logic states on the control input. The control signals are buffered by non-power-gated inverters before being applied to the input of a PGB. VPCs may propagate a control signal that is in phase with or inverted from a corresponding control signal at the control input. VPCs may be cascaded to create virtual power rails in chains and power grids. The control signals are latched at the cell boundaries or latched in response to a clock signal.Type: GrantFiled: August 26, 2004Date of Patent: October 2, 2007Assignee: International Business Machines CorporationInventors: Jente B.
