| Abstract | ||
| This research presents the possibility of using field programmable analog arrays in designing and executing a voltage controlled oscillator circuit. Field programmable analog arrays are distinguished for including all the mutual components necessary for processing analog signals. AN221E04 chip, the specification of which has been explained in this research, has been used in building up an advanced voltage controlled oscillator circuit. This circuit is distinguished for its simplicity, high stability degree, low power consumption, small size; in addition to decreasing the noise effect on the output circuit. Simulation of the proposed circuit has been completed according to Anadigm Designer2 software, and simulation results were shown on a programmable signal drawer, and the results were identical, which reflects the competency of the software used in the circuit. | ||
