Design and Simulation of High Frequency Tuned Amplifier

摘要

Aiming at the high-frequency tuned amplifier circuit difficultly designed by traditional methods, Multisim 10 easily compared the simulation data and real data. The suitable components of the amplification were selected by parametric scanning analysis. Measuring the max output voltage got tuning capacitor of the frequency-selection. Emulation analysis was conducted for frequency, voltage gain and band-pass, indicating that accomplishing the multi-input small signal amplification and frequency selection. Analyzing load resistance and junction capacitance Cbc, proposed methods of high quality and stability. The results indicate that the design method is reasonable and performance indicators to meet the design requirements.
