    Abstract

    Pengayun Terkawal Voltan, VCO merupakan salah satu aspek penting bagi blok binaan aplikasi komunikasi moden yang berwayar dan tidak berwayar dalam era komunikasi kini. Jelasnya, pengayun ini sentiasa dianggap sebagai nadi penting dalam komunikasi radio dua hala yang kini di dapati di pasaran (Scalpi, 2008). Usaha untuk menghasilkan reka bentuk VCO yang terbaik telah dijalankan secara intensif dan berterusan dari penemuannya hingga kini. Halangan yang paling mencabar adalah untuk mencari jalan penyelesaian dalam pengesahan rekabentuk pengayun terkawal voltan yang terbaik, teguh dan kos efektif selaras dengan permintaan pasaran semasa. Kajian ini memaparkan cara yang terbaik untuk megesahkan rekabentuk sistem pengayun terrkawal voltan yang mengunakan kaedah Colpitts supaya ianya cekap dan mantap. Penyelidikan ini juga menbincangkan aspek-aspek lain yang merupakan elemen penting yang memerlukan perhatian yang mendalam terhadap alat alat komunikasi seperti radio dua hala bagi memastikan rekabentuk VCO yang cekap dan teguh. ________________________________________________________________________________________________________________________ The Voltage Controlled Oscillation, VCO is one of the most important building blocks in modern communication applications such as the wired and wireless communications devices. The oscillator is always been regarded as the ‘heart’ of a two way radio communication devices currently available in the market (Scalpi, 2008). Along the years major effort to produce the best VCO design have been carried out intensively and progressively. The challenge is to find a solution in validating a design that is robust and efficient yet cost effective VCO design in par with the current market demands. This research highlights the best possible ways to validate a VCO design which is using the Colpitts VCO design topology. This validation proves that the VCO design is a robust and efficient. This research also discusses about the key areas that requires proper attention during the design of a VCO design for a two way radio communication devices to ensure that the design is robust and efficient.
