Patent number: 6708253Abstract: A processor memory system which includes: a processor component provided with a processor and at least a first integrated RAM memory, at least one second, external memory which is coupled to the processor component via an interface, a programmable memory management component which is integrated in the processor component and checks, in the case of a data address requested by the processor, whether this data address is stored in the first RAM memory which serves as a fast memory and in which data from the external memory has been loaded in advance, wherein the memory management component indicates the RAM memory address at which the data associated with the memory address is stored if the data is present in the RAM memory, the data then being read from the RAM memory, and wherein, if the data address is not present in the RAM memory, the memory management component outputs an interrupt instruction to the processor which subsequently initiates the loading of the searched data address from the external memoType: GrantFiled: August 14, 2001Date of Patent: March 16, 2004Assignee: Koninklijke Philips Electronics N.VInventors: Axel Hertwig, Harald Bauer, Urs Fawer

Patent number: 6551881Abstract: A self-aligned dual-oxide UMOSFET device and a method for fabricating the same which includes a gate in the trench which self-aligns the channel body doping region and its associated body-drift region junction, the region for depositing the gate insulating layer, and the depth of ledge for the field layer step for a sidewall of a trench using a multiple-energy large angle tilt implant (LATid) technique. One of the energy levels of the LATid technique is optimized to damage a top silicon nitride layer of the LOCOS mask. The other energy levels of the LATid technique are for the formation of the channel body region in substrate mesas adjacent the trench. Implantation occurs using the same tilt angle for the implantation of the channel dopant at the multiple-energy levels.Type: GrantFiled: October 1, 2001Date of Patent: April 22, 2003Assignee: Koninklijke Philips Electronics N.V.Inventor: Tod Letavic

Patent number: 6498533Abstract: A bootstrapped dual-gate Class E amplifier circuit includes a first MOSFET and a second MOSFET connected in series and coupled between a dc voltage source terminal and a common terminal. An rf input signal terminal is coupled to a gate electrode of the first MOSFET and a dc control voltage terminal is coupled to a gate electrode of the second MOSFET, with a unidirectionally-conducting element such as a diode-connected MOSFET being coupled between a drain electrode and the gate electrode of the second MOSFET. The output of the amplifier circuit is taken from the drain electrode of the second MOSFET. This circuit configuration permits the first and second MOSFETs to withstand a larger output voltage swing, thus permitting the use of a higher supply voltage and resulting in a substantially increased maximum output power capability for a given load value.Type: GrantFiled: September 28, 2000Date of Patent: December 24, 2002Assignee: Koninklijke Philips Electronics N.V.Inventor: Tirdad Sowlati

Patent number: 5864219Abstract: A circuit for detecting a level of an input direct voltage comprises a comparator for comparing the input direct voltage with a reference signal, which by means of an integrator is derived from pulses whose charge quantity is variable in dependence on a comparator direct voltage. The reference voltage has a d.c. component and an a.c. component. The comparator supplies comparator pulses of a given pulse duration when the d.c. component of the reference voltage is substantially equal to the input direct voltage. The level of the input direct voltage is determined from the charge quantity of the pulses and from the pulse duration of the comparator pulses.Type: GrantFiled: February 28, 1997Date of Patent: January 26, 1999Assignee: U.S. Phillips CorporationInventor: Helmut Fink
