A GFSK Demodulator for Low-IF Bluetooth Receiver
An efficient mixed-mode Gaussian frequency-shift keying (GFSK) demodulator with a frequency offset cancellation circuit is presented. The structure is suitable for a low-IF Bluetooth receiver and can also be applied to other receivers involving continuous phase shift keying (CPSK) signals. The demodulator implementation is robust to tolerate process variations without requiring calibration. It ...

متن کاملThe Challenges of Precision Analog Modulation Measurement
In today’s digital world, many established analog techniques are being replaced by modern digital alternatives. Digital modulation is now commonplace, particularly in mobile communications, but traditional analog amplitude and frequency modulation are still in widespread use. Laboratories performing RF calibration report that analog modulation meters and analyzers are a part of their workload t...
متن کاملA 3-30 MHz Tunable Continuous-Time Bandpass Sigma-Delta A/D Converter for Direct Conversion of Radio Signals
modulators are still limited to IFs of several tens of megahertzs [6], [9]. The disadvantages of the CT approach are less accuracy and lower dynamic range. Abstract— In this paper we present the design and simulation results of a CMOS fourth-order bandpass deltasigma modulator, intended for the A/D conversion of RF signals directly coming from a shortwave receiver antenna. The modulator tuning ...
متن کاملNon Contiguous Tri-band Receiver for Carrier Aggregation RF System
The carrier aggregation technique will allow an increase of capacity of the 4 Generation mobile communication networks (LTE-A: Long Term Evolution Advanced). The probability to find carriers that occupy a continuous spectrum in frequency is very low. The challenge is to demodulate an RF signal where the information is distributed on non-contiguous frequency bands. The technique presented in thi...
