Japanese Patent JPH0779209
Kind Code:
B2
Abstract:
PCT No. PCT/EP90/00058 Sec. 371 Date Jul. 12, 1991 Sec. 102(e) Date Jul. 12, 1991 PCT Filed Jan. 11, 1990 PCT Pub. No. WO90/08429 PCT Pub. Date Jul. 26, 1990.The invention relates to a temperature-stable transistorised tuned-circuit oscillator. Provided for the purpose of temperature stabilisation of the tuned-circuit voltage is a transistor T2, which is thermally coupled to the tuned-circuit coil L and controls a current source Q in the circuit of the oscillator L, C1, T1, in such a way that temperature-induced variations of the data of the tuned-circuit coil L are compensated.
