<p>A Voltage Controlled Oscillator for wide range tuning bandwidth comprises a transistor (T1) with a voltage tunable resonant circuit (D1, D2, L1) connected to an emitter of the transistor (T1) and inductive elements (L3, L4) connected to the collector of the transistor (T1). The collector is fed back to the base of the transistor (T1). The feedback path comprises the series connection of two capacitors (C1, C2) and a resistor (R1). A circuit node (N3) between the capacitors (C1, C2) is inductively coupled to the base of the transistor (T1).</p> |
