摘要: | 此一設計由互補式-金屬-氧化-半導體(CMOS)電晶體構成,而電路之基本 原理係利用CMOS電晶體的平方律原則設計,共包含了乘法器電路,電壓- 電流與電流-電壓轉換電路,相位延遲電路,限制放大器電路,濾波器電 路以及數位的解調電路。 An all-CMOS FSK receiver IC has been designed and tested. It employs the square-law characteristic of CMOS transistors in saturated mode. The mixed-mode IC couples many functional blocks , a few linear voltage-to-current and current-to-voltage converters, one phase splitter for I-Q demodulation, one operational amplifier as an integrator in the phase-locked loop, a limiting amplifier before FSK signal demodulation, two cascaded sixth-order low-pass filters employing four 'Gm-C' elements, and a digital combinational logic for decoding the FSK signals coming out of the limiters in both I-Q arms. |
