Variable Frequency Oscillator Circuit at Isabelle Odonovan blog

Variable Frequency Oscillator Circuit. Tuning the variable frequency oscillator (vfo) the feedback trim capacitor c4 will be adjusted just to start and maintain the. Art to get maximum frequency shift while retaining the frequency stability that crystal oscillator circuits are known for. In figure 3 this is achieved by using the positive temperature coefficient of a small lamp to regulate gain as the output. Frequencies ranging from several hz to several khz can be obtained using this circuit. C2 is a trimmer capacitor used to adjust the desired tuning range. For very low frequencies (few hz) replace c with a higher value. It operates from 1 khz to 20 mhz. Stable variable frequency oscillator can replace a crystal oscillator. Loop gain is maintained at unity at the oscillation frequency. The basic lc resonant circuit that determines the frequency is c1 and l1. The output frequency is programmable via a single resistor and the. This chapter summarizes what i learned in my odyssey through six vfo prototypes.
