“…Traditionally, the injection pulling has been avoided in conventional frequency synthesizers for cellular applications through careful frequency planning, such as in [5], but this workaround fails without the fixed FREF assumption. The 400-kHz spur affecting the alternate adjacent channel in global system for mobile communication (GSM) is particularly troublesome because of the tough -dBc requirement of the modulated phase noise in the 30-kHz bandwidth around the 400-kHz offset from the carrier.…”

“…This specification usually establishes the GSM frequency synthesizer architecture and drives the phase noise and spurious specs of its blocks. The injection-pulling 400-kHz spur, although it appears only twice in the 65 channels between the 13-MHz reference, was instrumental in [5] in selecting a dual integer-PLL structure, instead of a simpler fractional-PLL.…”

We propose and demonstrate a Gaussian frequencyshift keying and Gaussian minimum-shift keying (GMSK) pulseshape filtering for wireless RF transmitters with an arbitrary reference frequency. The filter is software controlled to work in a multistandard radio. Spurs, which are due to the frequency injection pulling, in cases when the reference harmonics are close enough to the oscillating frequency, are avoided by means of retiming the reference clock by the RF oscillator. Baseband clock for the pulse-shape filtering is derived through a simple fractional-N division of the reference frequency. This saves area and power since it is no longer required to create a low-jitter clock for baseband symbol generation and modulating data. It is especially advantageous when the available reference frequency is not an integer multiple of the symbol rate. The presented transmitter is realized without any explicit analog filtering and is part of a commercial single-chip fully compliant Bluetooth radio fabricated in a digital 130-nm CMOS process. We demonstrate the software programming capability through an experimental GMSK modulation for the global system for mobile communication.Index Terms-Bluetooth, frequency synthesizers, Gaussian frequency-shift keying (GFSK), Gaussian minimum-shift keying (GMSK), global system for mobile communication (GSM), interpolation, injection pulling, pulse-shaping filter, retiming, software defined radio, transmitter.

In this paper a WCDMA/GSM/DCS/PCS multimode frequency synthesizer is presented. It consists in a double loop synthesizer with a programmable divider between each integer synthesizer in order to provide fractional steps. The synthesizer has been implemented in a STMicroelectronics 0.25 µm RF BiCMOS technology. Measured phase noise at 400 kHz of the 3.8 Ghz carrier is -118 dBc/Hz. Power consumption is about 21 mA from a 2.5 V battery.

“…The goal is to modulate the Voltage Controlled Oscillator (VCO) of a PLL either by replacing the crystal reference by a frequency modulator as in TX Loop [2], or to drive the divider thanks to a Sigma Delta (Σ∆) modulator [3] as shown in Fig. 2.…”

A high speed Direct Digital Synthesizer (DDS) based transmitter architecture is presented. The DDS driven by a Sigma Delta (Σ∆) locks by injection an LC-tank Oscillator on an upper harmonic. Moreover, the Injection Locked Oscillator (ILO) provides a band-pass filtering within its locking range which rejects out of band Σ∆ quantization noise. The DDS is detailed in order to explain how to design an output signal frequency close to the clock frequency. Then the architecture is modulated thanks to constant envelope modulation. Finally, ILO output is compared to high constraint mask such as GSM/DCS in order to simulate architecture capability.
