The voltage - controlled oscillator and the dual - modulus prescaler are the most crucial blocks in the pll frequency synthesizer. two kinds of voltage - controlled oscillator ( the quadrature voltage - controlled oscillator based on symmetrical spiral inductors and differential varactors, and the voltage - controlled oscillator with wide tuning range based on mos varactors ) and two kinds of prescaler ( the prescaler using phase - switching techniques, and the prescaler using dynamic circuit techniques ) are proposed. then, the complete pll frequency synthesizer is implemented, in which
壓控振蕩器和雙模預分頻器是鎖相環型頻率合成器中最關鍵的兩個模塊，本論文分別實現了兩種類型的壓控振蕩器（採用對稱螺旋型電感和差分二極體型容抗管的正交壓控振蕩器和使用mos型容抗管的大調諧范圍壓控振蕩器）和兩種類型的雙模預分頻器（使用相位開關技術的雙模預分頻器和使用動態電路技術的雙模預分頻器） 。 -
It is presented that the theory and the manufacturing technology of such analog phase shifter, which are made from conventional 3db quadrature hybrids coupler with two identical varactor - diode networks to provide a shifted phase that varies continuously with biased dc voltage. several analog phase shifters have been made for different operating frequencies. each phase shifter has phase range more than 180, return loss better than - 20db, insertion loss 4. 8db including 3db attenuator, transmission difference less than0. 075 db. computer code phases. bas can present the referenced component values
