754,713. Transistor generating circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 3, 1954 [Feb. 6, 1953], No. 3222/54. Class 40 (6). In a circuit arranged to oscillate above the " cut-off " frequency, a capacitor C, Fig. 1, and inductor L are connected between emitter e and base b to form a low impedance series resonant circuit, so that the impedance as seen from the collector constitutes a parallel resonant circuit. In a modification, Fig. 2 (not shown), the collector is connected to a tap on the inductor L and in a further modification, Fig. 3 (not shown), the capacitor C is replaced by two capacitors in series, the collector being connected to the junction point. |
