International Classification:
G01R 27/26 G01R 27/08
US Classification:
324658, 324709
Abstract:
Apparatus for sensing a current across a known resistor including a switched capacitor network and an amplifier having an input coupled to an output of the switched capacitor network. The switched capacitor network is configured to sample first and second reference potentials indicating the current. The amplifier is configured to produce first and second amplified potentials at an output of the amplifier based on the first and second reference potentials.

International Classification:
G08B 5/00 G08B 5/22
US Classification:
34081546, 3406911, 3406916, 455566
Abstract:
A light modulation system as described herein can be incorporated into a personal or portable electronic apparatus such as a cellular telephone, a digital music player, or the like. The light modulation system controls the activation of light elements, such as light emitting diodes, of the host electronic apparatus in response to one or more analog audio signals available at the host electronic apparatus. The analog audio signals may be obtained from any suitable analog audio path or source in the host electronic apparatus. The light modulation system is compact, inexpensive to implement, and need not rely on digital signal processors for operation.

Assignee:
Freescale Semiconductor, Inc. - Austin TX
International Classification:
H03M 1/12
US Classification:
341155, 341122
Abstract:
A system and method for converting an analog signal to a digital signal is provided including a first circuit () having a signal range and an input for receiving a first signal, and a second circuit () having an input receiving the analog signal and a first output coupled to the input of the first circuit. The first circuit () includes an amplifier (). The first circuit () samples the first signal and produces the digital signal from the first signal using the amplifier. A second output of the second circuit () is coupled to the amplifier (). The second circuit () samples and scales the analog signal via the amplifier () to produce the first signal within the signal range and cancels an offset of the first signal. The system and method reduce power consumption and save device area.

International Classification:
H03M 1/12
US Classification:
341155, 341163
Abstract:
A method and apparatus are provided for reducing the size and power of cyclic analog-to-digital converter (ADC) conversion circuits. During each cycle, the ADC conversion circuit generates a plurality of bits. The improved ADC includes a scaling/reference circuit having a single operational amplifier which operates in a reference generation mode and an analog multiplexing mode during generation of the first bit and operates in the analog multiplexing mode during generation of the subsequent bits.
Enhanced Range-Velocity Finding In Frequency-Modulated Continuous Wave Radar
SEMICONDUCTOR COMPONENTS INDUSTRIES, LLC - Phoenix AZ
International Classification:
G01S 13/58 G01S 13/931 G01S 7/35
Abstract:
A radar detection method that comprises receiving a signal from each of one or more receive antennas, each received signal including a plurality of chirps, each received signal corresponding to a transmit signal reflected by a reflector; obtaining a range signal by downmixing each received signal with a reference chirp signal; performing a frequency transform on the range signal to obtain, for each chirp in the plurality of chirps, a set of range coefficients; compressing each set of range coefficients to obtain a plurality of compressed coefficient sets, wherein each compressed coefficient set corresponds to a set of range coefficients; storing each compressed coefficient set in a buffer; decompressing each compressed coefficient set to obtain buffered sets of range coefficients; processing the buffered sets of range coefficients to determine a range to a reflector of the transmit signal; and reporting the range to an electronic control unit.
