<p>An oscillator voltage regulator includes a substantially constant voltage device (D1) in series with the bias network dividing resistors (R1 & R2) to reduce current flow and provide a substantially constant voltage drop, and an impedance (R3) connected between the first and second resistors of the dividing resistors (R1 & R2) and the tank circuit (T) and the base of the amplifier transistor (A) so as to reduce the loading on the tank circuit and so as to improve stability, reduce phase noise, and increase power output from the amplifier. The use of silicon PN junction (D1) and a NPN transistor (A) provides temperature compensation for hot and cold ambients to allow the oscillator to operate substantially a constant supply current (I4).</p> |
