摘要： Embodiments provide apparatuses, systems, and methods to convert an analog signal input into a sigma-delta digital output at a high sampling rate and correct for noise components of the digital output. An analog filter coupled to a sigma-delta converter accepts a noise-shaped analog signal from the sigma-delta converter to attenuate signal components of the noise-shaped analog signal at a plurality of folding frequencies associated with a sampling rate of a low-speed Analog-To-Digital (ADC) to produce a filtered output. The low-speed ADC is coupled to an output of the analog filter and samples the filtered output of the analog filter at a sampling rate slower than the high sample rate to output an ADC digital output. Other embodiments may be described and claimed.

摘要： Disclosed is a package having a thin film bulk acoustic resonator (FBAR). The package may be utilized for suppressing spurious resonance occurred during operation of the FBAR. The package includes a negative impedance converter (NIC) operatively coupled to the FBAR through at least one interconnect. The at least one interconnect includes transmission lines and bonding wires. The package further includes a filter operatively coupled to the NIC. The filter exhibits a parallel resonance at a predefined frequency. The parallel resonance exhibited by the filter is converted to a series resonance by the NIC such that the series resonance of the NIC is responsible for suppressing the spurious resonance occurring during the operation of the FBAR.
