Abstract:
PCT No. PCT/FI97/00276 Sec. 371 Date Jul. 6, 1998 Sec. 102(e) Date Jul. 6, 1998 PCT Filed May 7, 1997 PCT Pub. No. WO97/44235 PCT Pub. Date Nov. 27, 1997An emitter-coupled multivibrator circuit comprises two transistors (Q1, Q2), between which is provided a positive feedback by connecting each transistor base to the collector of the other transistor. In the multivibrator, the transistors (Q1, Q2) are connected to operating voltages via coils (L1, L2, L3, L4) instead of using conventional resistors and current sources. This lowers the necessary operating voltage, since no DC voltage loss is provided across the coils. Additionally, this improvement increases amplification during the avalanche process and thus the speed of the whole circuit. Further, the waveform of a signal is closer to the sinusoidal form at high frequencies. The speed of the circuit can be increased further by providing an electromagnetic coupling between the coils (L1, L2, L3, L4).
