20100026377 | CIRCUIT AND METHOD FOR PROVIDING A DESIRED VOLTAGE DIFFERENCE, CIRCUIT AND METHOD FOR DETECTING, WHETHER A VOLTAGE DIFFERENCE BETWEEN TWO VOLTAGES IS BELOW A DESIRED VOLTAGE DIFFERENCE, AND PROTECTION CIRCUIT - A circuit for providing a desired voltage difference in dependence on a reference signal, the circuit including a first resistor; a second resistor; a regulation circuit configured to regulate a current flowing through the first resistor, such that a voltage difference across the first resistor is determined by the reference signal; and a current mirror, wherein the current mirror is configured to mirror the current flowing through the first resistor to obtain a mirrored current flowing through the second resistor, such that the desired voltage difference is obtained across the second resistor. | 02-04-2010 |
20100148744 | STARTER CIRCUIT, BANDGAP CIRCUIT AND MONITORING CIRCUIT - Embodiments according to the present invention relate to a bandgap circuit, a starter circuit and a monitoring circuit for a bandgap circuit comprising a bandgap reference circuit comprising a first branch and a second branch, the first branch comprising a first node, the second branch comprising a second node, such that a potential at the first node is equal to a potential at the second node in an equilibrium of the bandgap reference circuit. The bandgap reference circuit further comprises a feedback node for a feedback signal and a feedback circuit coupled to the first and second nodes and adapted to provide a feedback signal to the feedback node based upon a comparison of the potentials at the first and second nodes. | 06-17-2010 |
