1 Objective
Voltage-Controlled Oscillator (VCO) Design: For this project, you will design and lay out a voltage-
controlled oscillator (VCO) using a discrete transistor. Your design should focus on achieving stable
oscillation with a frequency 900MHz, with an emphasis on practical circuit implementation and layout
techniques. We will use the Infineon BFP410 again (https://www.infineon.com/part/BFP410).
1. Start by selecting a suitable discrete transistor for your VCO design. Define your target frequency
range and outline your circuit topology (e.g., Colpitts, Hartley, Clapp, etc.).
2. You must use less than 20 mW of DC power.
3. Design the oscillator circuit, including calculation of all component values. Lay out the circuit,
considering parasitics and PCB layout best practices to minimize unwanted effects and optimize
performance. Analyze the output center frequency, the output phase noise and the DC power
consumption.
2 Requirements
1 Submit a concise report including a schematic diagram and PCB layout of your VCO circuit.
2 Your report should include detailed calculations for frequency range, component values, and a
discussion of layout considerations affecting performance (such as phase noise and frequency
stability).
