Bubba oscillator has the ability to generate the stable sine wave with low distortion using op-amp. The processing power of Bubba oscillator is quite small,therefore they often transmit in the frequency range from VHF to HF band. It is used in various application like mobile devices, power inverter, communication etc. In this paper we proposed a design of bubba oscillator using current feedback operational amplifiers (CFOA) at 12 MHz frequency. For this purpose we will use the AD844 IC and the simulation results are also shown along with ultiboard design and 3D-view of the proposed circuit. |
