There are three  primary areas to be addressed when higher performance and lower power  is desired. The first area is the device technology. Scaling of  devices has realized steady improvements for many years. The second  area is improved circuit design techniques. The final area is at the  architectural level. This monograph focuses on the problem of low  power GFSK\/GMSK modulation and presents an architectural approach for  improved performance. The new architecture is a modulated S-D  fractional-N frequency synthesizer. The key innovation is an automatic  calibration technique, which operates in the background. The  availability of the calibration circuit makes high data rate, low  power modulation possible. \u003cbr\u003e  \u003cstrong\u003eFrom the Foreword:\u003c\/strong\u003e \"The key contribution of the work presented  in this monograph is a technique for in service automatic calibration  of the modulated frequency synthesizer by ensuring that the digital  emphasis filter and analog loop filter characteristics are matched.  The automatic calibration circuit operates while the transmitter is in  service and compensates for process and temperature variation. GFSK  and 4-GFSK modulation was demonstrated at data rates of 2.5 Mb\/s and 5  Mb\/s respectively at an RF output carrier frequency of 1.8 GHz. ... In  addition, he presents some valuable tools for the practicing engineer  in this field.\" by  \u003cem\u003eCharles G.
