Method And Apparatus For Producing A Low-Noise, Temperature-Compensated Bandgap Voltage Reference

View page
US Patent:
2009003, Feb 12, 2009
Filed:
Aug 5, 2008
Appl. No.:
12/186290
Inventors:
GIOVANNI PIETROBON - Berkeley CA,
International Classification:
G05F 1/10
US Classification:
327539
Abstract:
A bandgap voltage reference circuit is achieved that does not resort to the use of resistors or regulation loops and is thus able to achieve improved noise performance while also exhibiting absolute stability, no start-up issues, and low input-voltage operation. Subcircuits comprised of four interconnected transistors of different junction areas are used to create differential base-emitter voltage sources with magnitudes that vary in direct proportion to absolute temperature. The voltages from several of these subcircuits are combined without resistors to create a voltage source that is proportional to absolute temperature. An additional transistor is operated as a forward-biased PN junction to create a voltage source that varies in a sense that is complementary to absolute temperature. By a judicious choice of the transistor-junction-area ratios and the number of subcircuits that are summed, the combination of the complementary and proportional voltage references produces a bandgap voltage reference that is nearly constant with variations in temperature. The unique summation technique presented results in a bandgap reference with a noise performance that is more than an order of magnitude better than the prior art, particularly for applications requiring low current consumption.

Short Circuit Protection Circuit For A Low-Side Driver Circuit

View page
US Patent:
6008972, Dec 28, 1999
Filed:
May 12, 1997
Appl. No.:
8/854667
Inventors:
Giovanni Pietrobon - Novi MI
Assignee:
STMicroelectronics, Inc. - Carrollton TX
International Classification:
H02H 300
US Classification:
361 931
Abstract:
A short circuit protection circuit which has a first short circuit protection circuit in parallel with a second short circuit protection circuit is disclosed. The first short circuit protection circuit includes a sense resistor and a comparator for detecting the short circuit, and a transistor and current source for turning off the low side driver when the short circuit is detected. The second short circuit protection circuit includes a current mirror, zener diode, transistor, and current source connected in series. The second short circuit protection circuit is in parallel with the first short circuit protection circuit. The second short circuit protection circuit accelerates the turn-off of the low-side driver with out affecting the stability of the circuit.

Adjustable Reset Threshold For An Integrated Regulator

View page
US Patent:
5502416, Mar 26, 1996
Filed:
Mar 31, 1995
Appl. No.:
8/414779
Inventors:
Giovanni Pietrobon - Novi MI
Assignee:
SGS-Thomson Microelectronics, Inc. - Carrollton TX
International Classification:
H03K 508
US Classification:
327538
Abstract:
According to the present invention, an integrated regulator having an adjustable reset threshold is disclosed. The integrated regulator has the following elements contained within an integrated circuit device: a transistor, a voltage reference block, an internal resistive network, an operational amplifier which regulates the voltage output signal of the integrated regulator by regulating the base current of the transistor, and a comparator which senses and communicates to the user when the operational amplifier is unable to maintain the voltage output signal within an acceptable range of a desired value of the voltage output signal. External to the integrated circuit device is an external resistive network. When the reset output signal of the integrated regulator is equal to an active state, this is indicative that the operational amplifier has been unsuccessful in keeping the voltage output signal within the acceptable range of the desired value of the voltage output signal, i. e. the voltage output signal has fallen below the reset threshold or trip point of the integrated regulator.
