An electronic circuit includes a fast-settling threshold estimator for determining a fast-settling threshold voltage which includes a maximum peak detector that receives an analog signal containing digital data and produces an estimate of a maximum value of the analog signal; a differentiator that produces an output voltage responsive to a change in the estimate of a maximum value of the analog signal; a preselected voltage coupled to a comparator that outputs a pulse when the output voltage is greater than the preselected voltage; a minimum peak detector that produces an estimate of a minimum value of the analog signal; and an averaging circuit that produces a weighted average of the estimate of a maximum value of the analog signal and the estimate of a minimum value of the analog signal. In one embodiment, the fast-settling threshold estimator is coupled to a bit slicer and to a RF receiver.

A continuous-time delta-sigma modulator (CTDSM) system includes a quantizer, an update block, a switching block, a summation block, and a feedback path. The quantizer is configured to quantize an analog input signal into one or more thermometer-coded digital signals. The update block is configured to generate control signals based on the thermometer-coded digital signals. The switching block is configured to route the thermometer-coded digital signals to a plurality of digital-to-analog converter (DAC) elements based on the control signals. The plurality of DAC elements is configured to convert the thermometer-coded digital signals into analog outputs. The summation block is configured to combine the analog outputs from the plurality of DAC elements to produce a final analog output. The feedback path is configured to use the final analog output as a feedback signal for the CTDSM system.

A transmitter reduces the Crest Factor of an input signal by identifying potentially hidden peaks and by efficiently identifying the delay between an observed peak at a specified sampling rate and a corresponding true peak generated after upsampling. The transmitter rescales, based on a programmable rescaling parameter, a threshold for peak detection, and employs the rescaled threshold to identify one or more candidate peaks of the input signal. After the transmitter has rescaled the one or more candidate peaks based on the estimated fractional delay between the candidate peaks and the corresponding true peaks, the peaks are reevaluated based on the original threshold.

One or more integrated capacitors can be formed within the molding material(s) of a molded electronic device package.

A second volume of molding material is formed above the first capacitor plate and a second capacitor plate is formed on a top surface of the second volume of molding material which separates the second capacitor plate from the first capacitor plate.

A system and method is presented for determining a plurality of MIMO virtual antenna arrays. Each virtual antenna array of the plurality of MIMO virtual antenna arrays is associated with a subset of a plurality of transmit antennas (102) and a subset of a plurality of receive antennas (104). Signals received by the plurality of receive antennas are used to determine signal spectrums (208) for each MIMO virtual antenna array of the plurality of MIMO virtual antenna arrays. Each signal spectrum includes signal magnitude values and has associated angle values, wherein main lobe (210) positions of the signal spectrums of the plurality of MIMO virtual antenna arrays are at a same angle across all signal spectrums and sidelobe (212) positions of the signal spectrums are not at the same angle across all signal spectrums. A first combined MIMO virtual antenna array signal spectrum (409) is determined by combining minimum values of the signal spectrums at each angle value. The first combined MIMO virtual antenna array signal spectrum is used to detect an object.
