Design LC oscillator for MF, HF& VHF using both ideal and practical operation amplifier

Abstract

In general, the oscillator is a device that used in most circuits and system of electronics, electrical, and telecommunications. There are several kinds of oscillator contingent on frequency band use in a submission such as microwave, audio, and radio frequency. LC oscillator is one of the greatest mutual categories of oscillators, the applications of this oscillator was seemed to be increasing in modern devices, for actual high and very high frequencies to meet the speedy growth of progressive knowledge. That can be secondhand for radio frequency (RF), its productivity signal is frequently applied at the basis of radio communication classification in furthermost applications. In this paper, a designed Colpitts oscillator is covered from voltage amplifier with LC container. This strategy is done by two approaches. Primarily, is approved out exploitation hypothetical scheming. The subordinate is supported out exploitation imitation (Multisim 13). There are two proposal types of circuits the first for generate signal frequencies 0.5MHz,1MHZ,10MHz,20MHz,50MHz &100MHz, the second for generate signal frequencies 4.963MHZ, 5.031MHZ, and 5.756MHz respectively. The consequence is realized to be very hopeful.
