Applications of Two-Point Delta-Sigma Modulation to FHSS Transmitters

Pan, Chi-Nan 09 July 2003 (has links)
In the first, a time-variant modulus phase lock loop(PLL) model is established. Applying the model, Theorems of fractional-N synthesizers are introduced. We also explain theorems and simulations of Closed-Loop Modulation and Two-Point Delta Sigma Modulation with the model. In the end, a 2.4GHz FHSS transmitter using Two-Point Delta Sigma Modulation which meets Bluetooth specifications is demonstrated.
