    摘要： A circuit and method control the common-mode potential at an output (17, 18) of a fully differential amplifier (32) by feeding forward a common-mode correction signal through the amplifier. An input signal (V.sub.IN+ -V.sub.IN-) is amplified in the amplifier to produce a differential output signal (V.sub.O- -V.sub.O+) at the output. A common potential of the differential inputs (37, 38) of the amplifier is sensed with a transistor (54, 56) biased to a reference voltage (V.sub.CM) and amplified through the amplifier to produce a common-mode correction signal to offset a common-mode component of the differential output signal. A feedback circuit (33-36) is used to develop the common potential from the common-mode component.

    摘要： A comparator (12) and method compare first and second signals (V.sub.IN+, V.sub.IN-) to provide an output signal (V.sub.O, V.sub.OB). A transistor (43) couples a supply terminal (64, 66) of the comparator to a power supply (V.sub.DD) to enable the comparator for comparing the first and second signals. When the output signal is valid, it turns off the transistor to isolates the supply terminal from the power supply. As a result, power is reduced and a change in the first and second signals is prevented from changing the output signal. When the transistor turns off, a charge is trapped on the supply terminal that unbalances the comparator and causes a comparison error. A balanced condition is restored with a discharge circuit (31-33) coupled to the supply terminal to alter the charge when a control signal (RESET) is applied.

    摘要： Embodiments are provided for utilizing speech analytics for automatically managing messages in a communications network. A message from a calling party to an unavailable called party is recorded in a messaging management module. The messaging management module automatically identifies a category for assigning to the content of the message based on information associated with the unavailable called party or a calling party and associates a language model with the message content based on the category. An analysis module utilizes the language model to identify grammar making up the message content. The messaging management module automatically performs a messaging management function on the message content based on a set of rules. The messaging management function may include automatically determining a priority for the message (enabling the message to be retrieved out of order) or automatically triggering an action in response to the message which is directed to the unavailable called party.
