Abstract: A biasing scheme for a MOSFET that mitigates the MOSFET body effect. The biasing scheme can be realized replicating the voltage at the source terminal of a MOSFET and applying this replicated voltage to the body terminal. In this manner, the effect of the body transconductance, at high frequencies, becomes a function of the ratio of the well-to-substrate capacitance of the MOSFET to the sum of the well-to-substrate capacitance and the source-to-body capacitance of the transistor. At high frequencies, the biasing scheme mitigates the reduction in gain of a source follower caused by the body effect of a driven MOSFET within the source follower, improves the stability of a feedback network established by a gain boosting amplifier and the driven MOSFET by contributing a negative half plane zero to the transfer function of the feedback network, and reduces the power consumed by the gain boosting amplifier.

Abstract: A CMOS gain stage includes biasing circuitry configured to insure saturation of a subsequent stage without a source follower circuit. The CMOS gain stage is optionally powered by a supply voltage that is greater than a permitted supply voltage for a processes technology that is used to fabricate the CMOS gain stage. In order to protect CMOS devices within the CMOS gain stage, optional drain-to-bulk junction punch-through protection circuitry is disclosed. A variety of optional features can be implemented alone and/or in various combinations of one another. Optional features include process-voltage-temperature (“PVT”) variation protection circuitry, which renders a gain relatively independent of process, voltage, and/or temperature variations. Optional features further include bandwidth enhancement circuitry.

Abstract: A system for receiving signals (e.g., optical signals) includes an input device, an amplification device, and a feedback device. The amplification device receives a signal from the input device and includes a transimpedance portion. The transimpedance portion includes a first section having a plurality of elements (e.g., resistors and transistors) and a second section having a plurality of elements (e.g., resistors and transistors). One or more of the elements (e.g. transistors or resistors) in the first and second sections are mismatched to introduce a systematic offset in the transimpedance stage, to make the net input referred offset of the amplification device unidirectional. The feedback device (e.g. an integrator) is coupled to an output of the amplification device and an input of the transimpedance portion to provide a unidirectional offset correction to the amplification device for reduced noise enhancement.

Abstract: The present invention relates to a replica network for linearizing switched capacitor circuits. A bridge circuit with a MOSFET resistor disposed in a resistor branch of the bridge circuit is provided. A noninverting terminal of an operational amplifier is connected to a first node of the bridge circuit and an inverting terminal of the operational amplifier is connected to a second node of the bridge circuit. The second node is separated from the first node by another node of the bridge circuit. An output of the operational amplifier is provided to a gate terminal of the MOSFET resistor and to the gate terminal of the MOSFET switch in a switched capacitor circuit, thereby controlling the resistance of the MOSFET switch so that it is independent of the signal voltage. In this manner, the replica network of the present invention linearizes the switched capacitor circuit. In this manner, the replica network of the present invention linearizes the switched capacitor circuit.

Abstract: The invention includes a full duplex transceiver for transmitting and receiving communication signals. The transceiver includes 1 to N sample and hold circuits. Each sample and hold circuit receives a first signal that includes a far-end signal, and in some cases an echo signal, and in some cases alternatively or additionally cross-talk signals. The transceiver additionally includes a plurality of subtraction circuits. Each subtraction circuit receives an output of at least one of the sample and hold circuits. Each subtraction circuit subtracts at least a fraction of a replica signal from at least a fraction of the output of the at least one of the sample and hold circuits. The subtraction circuits generate an output that represent the far-end signal with substantially reduced echo and/or cross-talk interference, and is available for additional receiver processing.

Abstract: A system, method and computer program product for ensuring the quality of services being provided by a protected network of computers during an ongoing security breach is provided. The quality of the services is ensured by performing secure Quality of Service actions on data packets on the network. The sQoS actions depend on whether the data packets correspond to an attack on the computer to which they are directed, called the destination computer. If the data packet corresponds to an attack, then the actions also depend on the type of attack. In case there is no attack, the actions depend on the history of attacks by data packets that had originated from the same source computer and were directed towards the same destination computer. Supported actions include HardenFW, ControlBW and ConnectionLimit.

Abstract: The present invention provides a system, method and computer program product for managing customers in a hierarchical manner. The customer hierarchy comprises a root service provider (RSP), tiered service providers (TSPs) and end customers. The present invention enables the governing of the customers by a large service provider by providing an ability to make smaller service providers as customers and managing their resources. The smaller service provider, in turn, can have its own customers. The smaller service provider governs these customers without interference from the service providers above it in the hierarchy. The customers are governed by policies. A policy is a set of rules laid down by the service provider to control the customers. The present invention also enables the service provider to implement different policies on different customers and change the policy for a customer without affecting other customers.
