Colpitts Oscillator Calculator

Colpitts oscillator circuit is shown in Figure 1, Q is the transistor. The Colpitts and Hartley oscillator circuit are similar, except the inductor, capacitor exchange of positions. Oscillator equivalent circuit shown in Figure 2. Figure 1 Figure 2 Capacitors C1, C2, and inductor L form a positive feedback network of selected frequency, feedback signals from […]

Hartley Oscillator Calculator

Inductive three-point oscillator circuit, also known Hartley oscillator circuit. Figure 1, Q is the transistor, L1, L2, C resonant circuit formed, L2 double as feedback network, through the coupling capacitor Cb will be sent to feedback voltage transistor base. Figure 1 Figure 2 Figure 2 shows the communication channel, resonant circuit with three endpoints and […]
