【Oscillator design function】 〜It designs oscillators of Colpitts, Hartley, Klapp, and series feedback types. 〜 ● ● It can select the transistor from the library. ● It can design Colpitts, Hartley, Klapp, and series feedback type oscillators. ● The transmission lines such as the micro strip can be used with the series feedback type.

【Example of 300 MHz LC Klapp oscillator design】 ● ● This is a design example of a 300 MHz Klapp circuit. ● This is designed using the S parameter in the library and simulated with the linear circuit. ● It cuts off a part of the feedback loop and simulates the loop gain and feedback phase. ● The graph shows the feedback phase is 0 degrees at 300 MHz. ● The figure below shows the circuit using the non-linear model rewritten according to the oscillating constant configured by Design. ● By transient analysis, the oscillating waveform and spectrum at 300MHz can be confirmed. 【Example of series feedback type oscillator design (electrical length line)】 ● ● This is a design example of a 1200 MHz series feedback type oscillator. ● It is designed with the electrical length line. ● The graph shows the negative resistance at 1200 MHz. ● The figure below shows the circuit using the non-linear model rewritten according to the oscillating constant designed by Design. ● The oscillating waveform can be confirmed by transient analysis.
