Abstract
1,170,608. Gunn effect pulse multiplier circuits. TELEFUNKEN PATENTVERWERTUNGS-G.m.b.H. 2 Nov., 1966 [15 Dec., 1965], No. 24503/69. Divided out of 1,170,607. Heading H3T. A Gunn effect pulse-multiplying circuit comprises a plurality of Gunn effect elements Pr1, Pr2 . . . connected in parallel with a D.C. bias source U and a common load resistance R1 means for applying a pulse to be multiplied to the first element Prl to initiate or interrupt oscillation in the element and thereby produce a voltage jump as output from the element, means for applying this voltage jump to the second element Pr2 to produce an output voltage jump from the second element ... and so on, the arrangement being such that each pulse applied to the first element produces across the common load resistance R1 a number of pulses corresponding to the number of elements Pr. In the circuit illustrated, each element Pr has an insulated control electrode St1, St2. . ., the pulse to be multiplied being applied to the electrode St1 and the output from each element being applied to the control electrode of the next element through a condenser C and an optional delay device VZ. In a modified circuit each control electrode forms a PN junction with the element.
