P-Type Source Bias Virtual Ground Restoration Apparatus

US Patent:
2010010, Apr 29, 2010
Filed:
Jul 13, 2009
Appl. No.:
12/501578
Inventors:
James Muha - Phoenix AZ, US
Jinhui Chen - Chandler AZ, US
Dwight Klaus - Phoenix AZ, US
Assignee:
MICROCHIP TECHNOLOGY INCORPORATED - Chandler AZ
International Classification:
H03K 19/0175
US Classification:
326 81, 326 62
Abstract:
A virtual ground restoration circuit is used to substantially eliminate excessive current from occurring in an integrated circuit device having two or more logic circuit modules in different voltage domains. Excessive current is caused when a signal between the two or more logic circuit modules in different voltage domains is at logic “0” and one of the logic circuit modules is biased at a voltage level above the true ground or common power source voltage, V, of the integrated circuit device.

Using Low Voltage Regulator To Supply Power To A Source-Biased Power Domain

US Patent:
2012022, Sep 13, 2012
Filed:
Mar 1, 2012
Appl. No.:
13/409440
Inventors:
James Muha - Phoenix AZ, US
Tim Wilson - Chandler AZ, US
DC Sessions - Phoenix AZ, US
Yong Yuenyongsgool - Gilbert AZ, US
International Classification:
G05F 1/10
US Classification:
323282
Abstract:
A common (ground) of a low voltage regulator is connected to a virtual common (ground) of an integrated circuit device that is also connected to transistor sources but isolated from a true ground connected to the substrate of the integrated circuit device. The regulated output voltage from the low voltage regulator rises the same as the virtual ground voltage rises when back-biased sufficient to reduce leakage current to an acceptable level in a given process technology. Therefore, the output of the low voltage regulator will maintain a normal operating voltage for the logic during a power saving back-biased condition.
