Voltage Regulator Startup Method And Apparatus

View page
US Patent:
7855542, Dec 21, 2010
Filed:
Jul 17, 2007
Appl. No.:
11/778799
Inventors:
Benjamin Heilmann - Raleigh NC, US
Assignee:
Qimonda AG - Munich
International Classification:
G05F 3/16
G05F 1/40
US Classification:
323316, 323281, 327539
Abstract:
A voltage regulator circuit comprises an amplifier, bias network and startup circuit. The bias network is configured to generate a bias voltage for setting a bias current in the amplifier. The startup circuit is configured to mirror the amplifier bias current and to assist the bias network in setting the amplifier bias current based on the mirrored amplifier bias current until the bias voltage approximates a desired level.

US Patent:
8120985, Feb 21, 2012
Filed:
Mar 12, 2008
Appl. No.:
12/046870
Inventors:
Christopher Kunce - Wake Forest NC, US
Benjamin Heilmann - Raleigh NC, US
Alan Daniel - Durham NC, US
Assignee:
Qimonda AG - Munich
International Classification:
G11C 8/00
US Classification:
36523003
Abstract:
In one embodiment, a memory device comprises a semiconductor substrate, a first set of memory banks disposed on the semiconductor substrate and a second set of memory banks disposed on the semiconductor substrate. Each memory bank of the second set is split into a plurality of memory bank segments physically separated from each other and from the first set of memory banks. Each memory bank segment is arranged adjacent to, and occupies less area than, one of the memory banks of the first set.

US Patent:
20080136396, Jun 12, 2008
Filed:
Dec 6, 2006
Appl. No.:
11/567327
Inventors:
Benjamin Heilmann - Raleigh NC, US
International Classification:
G05F 1/652
US Classification:
323298
Abstract:
A voltage regulator is operated by determining if the voltage output by the voltage regulator is within a desired operating region and adjusting a feedback resistance associated with the voltage regulator when the voltage output by the voltage regulator is outside the desired operating region.

Method And Apparatus For Enabling A Voltage Regulator

US Patent:
20090021229, Jan 22, 2009
Filed:
Jul 17, 2007
Appl. No.:
11/778805
Inventors:
Benjamin Heilmann - Raleigh NC, US
International Classification:
G05F 1/565
US Classification:
323280
Abstract:
A voltage regulator circuit is operated by enabling a bias network operable to set a bias current in an amplifier. A startup circuit is connected to the bias network, the startup circuit operable to assist the bias network in setting the amplifier bias current during a startup period. The startup circuit is disconnected from the bias network responsive to the startup period lapsing while the voltage regulator circuit is enabled for resetting the startup circuit to an initial state. The bias network may be disabled to reduce the amplifier bias current. Subsequent re-enablement of the bias network is prevented until the amplifier is reliably disabled.
