摘要： A method for providing a voltage reference at a present operating temperature in a circuit is provided. The circuit comprises a first MOS transistor having a first threshold voltage; and a second MOS transistor having a second threshold voltage different from the first threshold voltage is provided. Temperature insensitivity is obtained by compensating the difference between the first threshold voltage and the second threshold voltage with a parameter representative of the present operating temperature.

摘要： Disclosed are a temperature compensation apparatus and method. The apparatus includes a reference signal generator that supplies at least one of a first current which is constant regardless of temperature variation and a second current which is proportional to temperature variation, a slope amplifier that determines a first output current having a second temperature coefficient which is a multiple of a first temperature coefficient of the second current, based on the first current and the second current, and a slope controller that determines a second output current having a third temperature coefficient, using a weighted average of the first current and the second current.

摘要： An electronic switch is connected in series with a load dependent on an input signal. The electronic switch is operated in a first operation mode for a first time period after a signal level of the input signal has changed from an off-level to an on-level. The first operation mode includes driving the electronic switch dependent on a voltage across the load and dependent on a temperature of the electronic switch. The electronic switch is operated in a second operation mode after the first time period. The second operation mode includes driving the electronic switch dependent on the temperature according to a hysteresis curve.

摘要： A circuit and a method for regulating a voltage supply where the method includes the steps of concurrently measuring temperature, IR drop and frequency response within the circuit, adjusting voltage supplied to the circuit in response to the measured temperature, IR drop and frequency response, and determining a correction value based on the variance of the measured frequency response from an expected frequency response and providing a correction for subsequent predetermined frequency response values. The frequency response measurement is dependent upon the constant bandgap voltage source which may very according to temperature. Upon a determination that corrections may be required for the bandgap voltage source to compensate for temperature variations, the measurement process which uses the bandgap voltage source can be altered to compensate for the temperature variations.

摘要： Circuits and methods for paralleling voltage regulators are provided. Improved current sharing and regulation characteristics are obtained by coupling control terminals of the voltage regulators together which results in precise output voltages and proportional current production. Distributing current generation among multiple paralleled voltage regulators improves heat dissipation and thereby reduces the likelihood that the current produced by the voltage regulators will be temperature limited.
