RC-oscillator on the operational amplifiers manipulate FREQUENCY harmonic oscillations

摘要

Utility model RC-oscillator operational amplifier manipulated frequency harmonic vibrations relates to the field of electronics and can be used in radio transmission devices, and in measuring equipment as a source of harmonic oscillations keyed frequency. RC-oscillator comprises an operational amplifier (op amp), two power supplies, the three MOS transistors with channels induced n-type rectangular pulse generator, eleven resistors of constant resistance, three fixed capacitors. When hopping drops 01 and 10 of the control voltage generator of rectangular pulses are generated without phase discontinuity manipulated in frequency the low-frequency harmonic oscillation frequencies f₁ and f₀ respectively, while f₁ f₀ The inventive generator implement in integrated form.
