Hi People!
Urgent help is needed. I have to make a Voltage Controlled Oscillator with Frequency varying Around 500 Khz or higher (more is better) and sinusoid output.
The problem is: I can only use transistors, capacitors, diodes, inductors and resistors (no varactors, Integrated Circuits etc. ) I want to make something simple (5-6 transistors at most), but all circuits I find on the web, either use varactors or IC's, or they are too complex for my level of knowledge (I just can't analyze them).
Any advise would be very appreciated. Maybe anyone has done something similar?
Thank you.
