Filed:

Feb 23, 2010

Appl. No.:

12/710682

Inventors:

Cetin Kaya - Plano TX, US
Michael Pate - Allen TX, US

Assignee:

TEXAS INSTRUMENTS INCORPORATED - Dallas TX

International Classification:

G05F 3/02
H01L 29/78
G01R 19/00
H03H 11/24

US Classification:

327543, 257 48, 324 7611, 327581, 257E29256

Abstract:

These various embodiments pertain to an FET having a plurality of fingers as correspond to the FET's source and drain. A first conductive lead electrically couples to a given one of this plurality of fingers while a second conductive lead electrically couples as well to this same given finger. A measurement component connects to these first and second conductive leads to measure at least one electrical parameter (such as voltage). By one approach, the first and second conductive leads physically connect to opposing ends of the given finger. These teachings will also accommodate providing a control component that is responsive to the measurement component to facilitate automatically controlling at least one operating state of the FET as a function, at least in part, of the measured electrical parameter.

International Classification:

H03F 99/00

US Classification:

Abstract:

An output power limiter system (PLS) for audio amplifiers may be designed as a feedback control system for protection of the load and/or quality of the audio experience. The PLS may use comparator to sense the output current, compare it to a specified threshold, and assert a signal when the output current reaches and exceeds the specified threshold. The output signal from the comparator may enable a counter that is clocked with a high frequency clock to begin counting to measure the pulse-width of the comparator output. The output of the counter may be averaged through a fast attack and slow release infinite impulse response (IIR) filter having programmable settings to generate a rate of attenuation or rate of release that adjusts a gain correction in terms of decibels (dB). The output of the IIR filter may then be used for attenuating the output current.

Appl. No.:

13/548963

Inventors:

Lingli Zhang - Austin TX, US
Michael Pate - Austin TX, US

International Classification:

G05F 1/10

US Classification:

307 35

Abstract:

A single integrated circuit includes a single boost converter, a first circuit, a second circuit, and a controller. The single boost converter supplies power to the first and second circuits. The controller receives an operational mode signal and in response to the operational mode signal, drives the single boost converter to respectively provide power to the first and second circuits. When the first and second circuits are simultaneously active, the controller manages an operation of the first circuit so that proper operation of the second circuit is maintained. The first circuit may be an LED flash driver, and the second circuit may be an audio amplifier, such as a Class-D audio amplifier. The controller manages an operation of the audio amplifier so that a sufficient amount of current is supplied to the LED flash driver for proper operation of the LED flash driver.

Abstract:

A microphone that includes a calibration signal generator that generates a calibration signal based upon a received invocation input. The calibration signal has known audio properties. The microphone also includes a transducer that converts sound energy into an electrical signal. An integrated circuit receives the electrical signal from the transducer. An external microphone interface provides the calibration signal to a device external to the microphone.
