摘要

本文介绍了一种用于高斯频率和最小移位键控(GFSK/GMSK)调制的Sigma - Delta (/spl Sigma/-/spl Delta/)合成器。关键的创新是一个在役自动校准电路,该电路可调谐锁相环(PLL)以补偿工艺公差和温度变化。该锁相环包括1.8 GHz压控振荡器(VCO)、/spl Sigma/-/spl Delta/调制器和校准电路,已在0.6微米BiCMOS集成电路中实现。测试芯片使用GFSK达到2.5 Mbit/s,使用4-FSK达到5.0 Mbit/s。

Automatic calibration of modulated /spl Sigma/-/spl Delta/ frequency synthesizers
This paper describes a sigma-delta (/spl Sigma/-/spl Delta/) synthesizer for Gaussian frequency and minimum shift keying (GFSK/GMSK) modulation. The key innovation is an in-service automatic calibration circuit which tunes the phase locked loop (PLL) to compensate for process tolerance and temperature variation. The PLL, including 1.8 GHz voltage controlled oscillator (VCO), /spl Sigma/-/spl Delta/ modulator, and calibration circuit has been implemented in a 0.6 micron BiCMOS integrated circuit. The test chip achieves 2.5 Mbit/second using GFSK and 5.0 Mbit/second using 4-FSK.
