Patent number: 8896148Abstract: One embodiment relates to an apparatus that includes at least one circuit block and a voltage source configured to supply a first voltage to the at least one circuit block. The apparatus also includes a power delivery unit configured to be selectively activated based on a whether a quantity of power is to be delivered from the power delivery unit to the circuit block. A control unit is configured to, upon a change in power consumption of the at least one circuit block, activate the auxiliary power delivery unit to deliver the quantity of power to the circuit block. The auxiliary power delivery unit can quickly supply large currents since it does not necessarily rely on slow control loops using voltage sensing. Rather, the auxiliary power delivery unit often delivers pre-calculated current profiles to respond to the timing characteristic of the change of power consumption and of the voltage regulator.Type: GrantFiled: June 22, 2010Date of Patent: November 25, 2014Assignee: Infineon Technologies AGInventors: Joerg Berthold, Peter Mahrla, Stephan Henzler, Vincent Gouin, Fan He

Patent number: 6874073Abstract: A method allows the use of inexpensive read-only memory together with rewriteable memory. To this end, a memory management logic unit interacts with a control unit, with a read-only memory and with a rewriteable memory. The data, in particular memory areas of the read-only memory, have been replaced with data in the rewriteable memory. If the control unit accesses the replaced data in the read-only memory, the memory management logic unit diverts this access to the corresponding data in the rewriteable memory.Type: GrantFiled: May 7, 2003Date of Patent: March 29, 2005Assignee: Infineon Technologies AGInventor: Peter Mahrla

Patent number: 6492864Abstract: A circuit configuration for low-power reference voltage generation, is described. The circuit has a programmable voltage source which generates an output voltage which is compared with a reference voltage at predetermined times. Depending on the comparison, at least one signal, which is supplied to a control device, is derived by a calibration device. The control device programs the voltage source in such a manner that the output voltage corresponds to the reference voltage as closely as possible.Type: GrantFiled: April 1, 2002Date of Patent: December 10, 2002Assignee: Infineon Technologies AGInventor: Peter Mahrla
