    Abstract: An integrated circuit comprising a balanced differential amplifier. The balanced differential amplifier has a first single-ended differential amplifier coupled at a first negative differential input terminal to a first input signal through a feedback network also coupled to an output terminal of the first amplifier. The first amplifier is also coupled at a first positive differential input terminal to a second input signal through a first resistor and to a reference voltage. The balanced differential amplifier also has a second single-ended differential amplifier coupled at a second negative differential input terminal to the second input signal through a second feedback network also coupled to an output terminal of the second amplifier. The second amplifier is also coupled at a second positive differential input terminal to the first input signal through a second resistor and to the reference voltage.

    Abstract: A memory circuit includes an operational memory and a monitor circuit comprising a circuit element in the operational memory and/or a circuit element substantially identical to a corresponding circuit element in the operational memory. The monitor circuit is operative to measure at least one functional characteristic of the operational memory. A control circuit coupled to the monitor circuit is operative to generate a control signal which varies as a function of the measured characteristic of the operational memory. The memory circuit further includes a programmable voltage source coupled to the operational memory which is operative to generate at least a voltage and/or a current supplied to at least a portion of the operational memory which varies as a function of the control signal.

    Abstract: Disclosed is a circuit that adjusts a characteristic of a signal transmitted from a transmitter to a receiver over a communication channel (e.g., a wire, a backplane, etc.). The circuit includes a latch that receives the signal at a predetermined point in the circuit and samples a voltage of the signal many times after a threshold voltage is applied to the latch. The circuit also includes a processor that determines the characteristic of the signal when the sampled voltages indicate a transition point and that adjusts the threshold voltage when the sampled voltages do not indicate a transition point. The processor adjusts the characteristic of the signal by adjusting at least one of a current and a voltage of the transmitter when the characteristic of the signal is outside a predetermined range.

    Abstract: Communication techniques are provided. For example, in one aspect, a communication method comprises the step of inputting information, at the time of placing of a telephone call, that directs a receiving telephone to produce one or more of a plurality of incoming call indicators. The incoming call indicator, which may comprise a particular ring tone, can be used to signify one or more of an identity of a caller, a nature of the call and an importance of the call.
