20140003472 | DIGITAL FREQUENCY DEMODULATOR WITH LOW POWER CONSUMPTION AND RELATED SYSTEM AND METHOD | 01-02-2014 |
20130207699 | FREQUENCY-LOCKED SYNTHESIZER WITH LOW POWER CONSUMPTION AND RELATED SYSTEM AND METHOD - An apparatus includes a first oscillator configured to generate a reference signal and a second oscillator configured to generate an output signal having a controllable frequency. The apparatus also includes a frequency difference detector configured to generate a difference signal having a frequency based on a frequency difference between the reference signal and the output signal. The apparatus further includes a discriminator configured to modify the frequency of the output signal based on the difference signal. The frequency difference detector can be configured to generate the difference signal having multiple pulses. The discriminator can be configured to count a number of pulses in the difference signal during a specified time period and to modify the frequency of the output signal based on the counted number of pulses. The specified time period can be adjustable. | 08-15-2013 |
20090231060 | Ladder resonator filter and related system - An apparatus includes a plurality of resonators forming a filter. At least one of the resonators includes (i) a plurality of interdigital transducers positioned in a common acoustic track and (ii) a plurality of reflectors configured to reflect acoustic waves from the interdigital transducers back to the interdigital transducers. At least one reflector is positioned between adjacent interdigital transducers. The interdigital transducers in one of the resonators could be coupled in parallel or in series between an input and an output of that resonator. | 09-17-2009 |
