Demodulators inventions 07/08

20080169872 - Demodulator, chip and method for digital demodulating an fsk signal: A demodulator, chip and method for digitally demodulating an FSK signal utilizing a digital data transfer protocol and a digital demodulator circuit have been developed. The data-rate approaches the carrier-frequency. The one application for this technique is in the magnetically powered wireless systems such as biomedical implants and radio frequency... Agent: Brooks Kushman P.C.

20080169873 - High frequency signal detection circuit: A high frequency signal detection circuit includes an input terminal for a high frequency signal to be detected, a switch transferring the high frequency signal as intermittent ringing signal to a first node in response to a pulse signal whose frequency is lower than that of the high frequency signal,... Agent: Junichi Mimura Oki America Inc.

20080157867 - Individual channel phase delay scheme: Embodiments of the present invention are directed to processing an incoming signal by using a demodulation signal, while controlling the phase of the demodulation signal in relation to the incoming signal. The incoming signal can be processed by being mixed with the modulation signal at a mixer. The mixing may... Agent: Apple C/o Morrison And Foerster ,llp Los Angeles

20080157868 - Pll circuit, phase shifting method, and ic chip: A PLL circuit includes: a clock signal generating unit for generating a first clock signal and a second clock signal of which the phase differs from the first clock signal by π/2; a computing unit for computing first phase comparison results showing the results of comparing the phases of a...
