Constant Gm Circuits And Methods For Regulating Voltage

View page
US Patent:
8154263, Apr 10, 2012
Filed:
Oct 21, 2008
Appl. No.:
12/255468
Inventors:
Zhouyuan Shi - Santa Clara CA, US
Stephen Leeboon Wong - Saratoga CA, US
Assignee:
Marvell International Ltd. - Hamilton
International Classification:
G05F 1/59
US Classification:
323269, 323277, 323280
Abstract:
In one embodiment the present invention includes a voltage regulator circuit comprising a voltage to current converter. The voltage to current converter is coupled to provide a current to maintain an output voltage under changing load conditions. A transconductance of the voltage to current converter is independent of the output current and therefore improves stability for the voltage regulator across load conditions.

Switching Converter For Power Domain Separation

US Patent:
20210021194, Jan 21, 2021
Filed:
Jul 1, 2020
Appl. No.:
16/918917
Inventors:
- Limerick, IE
Jian Li - San Jose CA, US
Zhouyuan Shi - Fremont CA, US
Xu Zhang - Milpitas CA, US
International Classification:
H02M 3/158
H02M 3/07
Abstract:
A power domain isolation system, such as without requiring a transformer, can include a reactive circuit, an input network having first and second input nodes that are coupled in parallel with the reactive circuit via respective first and second current control circuits, and an output network having first and second output nodes that are coupled in parallel with the reactive circuit via respective third and fourth current control circuits. The first and second current control circuits can be configured to couple the reactive circuit to the input nodes when the third and fourth current control circuits are configured to electrically isolate the reactive circuit from the output nodes, and the first and second current control circuits can be configured to electrically isolate the reactive circuit from the input nodes when the third and fourth current control circuits are configured to couple the reactive circuit to the output nodes.

Dcr Inductor Current-Sensing In Four-Switch Buck-Boost Converters

View page
US Patent:
20170324331, Nov 9, 2017
Filed:
Jul 19, 2017
Appl. No.:
15/654568
Inventors:
- Milpitas CA, US
Jian Li - San Jose CA, US
Zhouyuan Shi - Fremont CA, US
Yi Ding Gu - Pleasanton CA, US
International Classification:
H02M 3/158
H02M 1/00
Abstract:
An inductor current-sensing circuit for measuring a current in an inductor includes (a) a first RC network coupled between a first terminal of the inductor and a reference voltage source; and (b) a second RC network coupled between a second terminal of the inductor and the reference voltage source. The first RC network and the second RC network each have a time constant substantially equal to the ratio between the inductance and the DC resistance of the inductor. The inductor which current is being measured may be a primary inductor of a four-switch buck boost converter receiving an input voltage and providing an output voltage.

Current Mode Switching Power Supply Having Separate Ac And Dc Current Sensing Paths

View page
US Patent:
20160164412, Jun 9, 2016
Filed:
Jun 30, 2015
Appl. No.:
14/755336
Inventors:
- Milpitas CA, US
Yingyi Yan - Fremont CA, US
Xu Zhang - Milpitas CA, US
Zhouyuan Shi - Fremont CA, US
International Classification:
H02M 3/158
Abstract:
In a current mode switching power supply, current through the inductor needs to be sensed to control the peak current. The inductor current includes a DC component and an AC component containing switching noise. To reduce the switching noise, the actual inductor current is sensed to generate a signal, and a first AC component is attenuated by a first RC circuit while not attenuating a first DC component. A second AC component is derived by applying the rectangular wave switch voltage, which is at the duty cycle of the regulator, to a second RC filter, which blocks a second DC component. The second AC component is much larger than the first AC component and does not contain switching noise. The large second AC component, the smaller “noisy” first AC component, and the first DC component are applied to the first RC circuit to create a low-noise inductor current signal.
