GPS navigation devices or GPS receivers can consume less power by using a temperature recorder circuit and/or a power manager in maintaining the accuracies of the GPS receiver time and reference frequency to improve battery life. A representative receiver includes a time reference device and the temperature recorder circuit that operate while the receiver hibernates. The time reference device generates clock signals and the temperature recorder circuit receives and operates using the clock signals from the time reference device. The temperature recorder senses the temperature of the time reference device. The temperature recorder circuit is designed to send a wake-up signal to at least one electrical component of the receiver to wake up the electrical component of the receiver. The electrical component of the receiver includes at least one of the following: a GPS signal processing system and a frequency reference device.

Systems and methods for managing power consumption

A resistive memory device. Implementations may include an array of memory cells including resistive memory elements which are coupled to isolation transistors and which may include a magnetic tunnel junction. A decoder decodes input address information to select a row of the array. A binarizer coupled to the memory array assigns binary weights to outputs of the memory array output through bit lines coupled to the memory cells. A summer sums the binary weighted outputs, and a quantizer generates an output digital code corresponding to data stored in a plurality of memory cells during a prior program cycle. The outputs of the memory array may be currents or voltages. In implementations multiple arrays of memory cells may be utilized and their respective outputs combined to form higher bit outputs, such as eight bit, twelve bit, sixteen bit, and so forth.

Resistive memory devices and related methods

Systems and methods for mitigating multipath signals in a receiver are provided. In this regard, a representative system, among others, includes a radio frequency (RF) front-end and at least one analog-to-digital converter (ADC). The RF front-end receives FM signals and down-converts the received frequency signals to intermediate frequency (IF) signals. The analog-to-digital converter (ADC) receives the intermediate frequency signals and digitizes multiple FM channels around a desired FM channel associated with the down-converted signals. The system further includes multiple sets of digital processing components that are configured to simultaneously receive and process the digitized multiple channels. The multiple sets of digital processing components include at least two parallel channel selection and demodulation paths in which the respective digitized multiple channels are processed therethrough.
